Alan Hayward d90b8f2632 Check arguments for all probes before using them
There is a long standing bug in the Arm toolchain where invalid
stap probes get created due to the probes referring to symbols which
have been resolved away.

More details are here:
https://bugzilla.redhat.com/show_bug.cgi?id=1196181

When these invalid probes are present, GDB will create the breakpoints
and then fail to stop. The errors are only spotted the first time
GDB stops, which is too late.

The solution is to ensure the arguments for all the probes are
resolved before using them.

This fixes >100 timeouts when running break-interp.exp when using
bad probes.

gdb/ChangeLog:

	* solib-svr4.c (svr4_find_and_create_probe_breakpoints): Check all
	probe arguments.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
