Fixes a few issues:
1) If you use "-fsanitize=address,undefined" in CFLAGS, the Makefile
attempt to trim off -fsanitize options left us with ",undefined".
2) ld_compile adds CFLAGS_FOR_TARGET itself, no need to pass it.
3) CFLAGS might be needed linking bootstrap test.

The top level Makefile, the ld Makefile and others, define
CC_FOR_TARGET to be a compiler for the binutils target machine. This
is the compiler that should be used for almost all tests with C
source. There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS
too. This was all supposed to work with the testsuite .exp files
using CC for the target compiler, and CC_FOR_HOST for the host
compiler, with the makefiles passing CC=$CC_FOR_TARGET and
CC_FOR_HOST=$CC to the runtest invocation.
One exception to the rule of using CC_FOR_TARGET is the native-only ld
bootstrap test, which uses the newly built ld to link a copy of
itself. Since the files being linked were created with the host
compiler, the boostrap test should use CC and CFLAGS, in case some
host compiler option provides needed libraries automatically.
However, bootstrap.exp used CC where it should have used CC_FOR_HOST.
I set about fixing that problem, then decided that playing games in
the makefiles with CC was a bad idea. Not only is it confusing, but
other dejagnu code knows about CC_FOR_TARGET. See dejagnu/target.exp.
So this patch gets rid of the makefile variable renaming and changes
all the .exp files to use the correct _FOR_TARGET variables.
CC_FOR_HOST and CFLAGS_FOR_HOST disappear. A followup patch will
correct bootstrap.exp to use CFLAGS, and a number of other things I
noticed.

The offset-within-section field in the symbol table entry is only 32
bits wide, so rather than emitting bogus entries omit them, and issue
a diagnostic identifying the issue.
This requires adjusting the PR/22267 test to no longer produce symbols
with out of range values on 64-bit BFD. This also depends on
adjustments to testsuite/ld-scripts/map-address.* made by an earlier
patch. The purpose of the test can very well be achieved nevertheless.
In PE images section addresses get expressed as addresses relative to
the image base. Therefore the VA of a section must be no less than the
image base, and after subtraction of the image base the resulting value
should fit in 32 bits. (The issue is particularly obvious to notice when
sections, perhaps because of ELF assumptions, get placed at VA 0 by
default. Debugging info sections as well as .comment, when input files
are ELF, are a good example. All such sections need proper mentioning in
the linker script to avoid this warning.)
There are a number of test cases which previously produced bogus images,
yet still declared the test a success. Like done for other tests
already, force a zero image base for these. This then also allows (and
requires) dropping again xfail-s which 39a7b38fac0e ("Fix linker tests
to work with 16-bit targets") had added to ld-scripts/default-script*.d
(originally as skip-s). This also depends on similar adjustments to
testsuite/ld-scripts/map-address.* made by an earlier patch.
For ld-scripts/print-memory-usage.* I suppose xcoff could be dropped
from the exclusion list by suppressing garbage collection, just like
already done in e.g. (as seen in the diff here) ld-scripts/data.*, but I
didn't want to make unrelated adjustments.
Without setting an image base address and without naming at least .text,
this test produces entirely bogus PE output. To be honest, even the ELF
output looks odd: .text gets placed at 0x10204, and both foo and bar get
associated with .text despite living below its start address.
Since neither image base nor .text placement are the subject of this
test, specify .text placement explicitly and in the PE case force the
image base to zero.

ld-elf/var1 and ld-scripts/pr14962.

"unresolved" as a test result means runtest returns an error, which
can be confusing when there is no apparent error unless you look in
.log files. In particular many tests are skipped without reporting an
error if no target C compiler is found, but if a target C compiler is
found but won't compile a testcase for some reason we used to mark the
test as unresolved. Which is no more worthy of an error than when
lacking a C compiler entirely.

I wanted to write a linker script like this:
PROVIDE(mem_origin = 0x1000);
PROVIDE(mem_length = 0x1000);
MEMORY
{
REGION : ORIGIN = mem_origin, LENGTH = mem_length
}
....
Then when I link using this script I can optionally supply:
--defsym=mem_origin=..... --defsym=mem_length=....
to override the defaults.
And though passing `--defsym' does work, if I remove the use of
`--defsym' and just rely on the defaults I get an error:
ld-new: invalid origin for memory region REGION
Interestingly, if I make the above error non-fatal and dump a linker
map file I see that (a) REGION has origin 0x0, and length 0xffff...,
and (b) the symbol from the PROVIDE is provided.
An examination of ldlang.c:lang_process shows us what the issue is,
the origin and length of all memory regions are set as a result of a
single call to lang_do_memory_regions, this call is done after calling
open_input_bfds.
During the open_input_bfds call provide statements can be converted to
provided statements if we know that the assigned symbol is needed, but
for symbols that are only used in the memory regions we are unaware
that we need these symbols.
What I propose in this patch is to make two calls to
lang_do_memory_regions, in the first call we process the expressions
for the origin and length fields of each region, however, errors,
especially undefined symbols, will be ignored. The origin and length
values are not updated. However, by evaluating the expressions any
symbols we need will be added to the symbol table.
Now when we call open_input_bfds, when we process the provide
statements, we will see that the assigned symbol is needed add its new
value to the symbol table.
Finally we reach the original call to lang_do_memory_regions, in
this (now second) call we again process the expressions, and this time
update the origin and length values. Any errors encountered now are
reported to the user.

lang_do_memory_regions, and pass parameter.

ERROR should really be reserved for errors in the testsuite framework,
not just normal errors from the tools under test. Removing use of
perror has been suggested before but without action, over concerns
that some test failures might be missed. This patch removes uses of
perror in ld_assemble, ld_compile and ld_nm, and updates numerous
places that ignored the result of these functions by inappropriately
returning an "unresolved" test status. Net result over my large set
of targets look good, in some cases improving the diagnostics, eg:

Also restore them somewhat closer to the original. They originally
failed on many targets, and a month later I "simplified" them as part
of a larger patch fixing other failing tests. That unfortunately lost
their main purpose, which was to test TLS layout.

m32c_md_end attempted to pad out a code section with nops, but this
was just plain wrong in many ways:
- The padding didn't happen at all if the last section emitted wasn't
a code section.
- The padding went to the wrong place if subsections were used, and
the last subseg used wasn't the highest numbered subseg.
- Padding wasn't added to all code sections.
- If the last section was empty, it was padded to 4 bytes.
- The padding didn't go to a 4-byte alignment boundary, instead it
effectively made the last instruction 4 bytes in size.
- The padding didn't take into account that code sections may have
contents other than machine instructions.
So, rip it out and handle nop padding properly, also fixing .align
.balign/.p2align in the middle of code.

This patch restricts the section names matched in coff_section_type,
a function that translates section names to symbol type, and arranges
to translate section flags to symbol type before looking at names.
The latter change resulted in various test failures due to improper
section flags being used in tests, and by the plugin support, so fix
that too.
The new test fails on many ELF targets that lack .init/fini_array
in their scripts. I've just xfailed those. pru-elf oddly defines
__init_array_begin rather than __init_array_start. I've left that
target as a FAIL, and pj-elf too which reports an error for undefined
weak symbols.
