* ldlang.c (entry_symbol_default): New file-scope global.
	(lang_finish): Use it, not a hardwired "start".
	(lang_default_entry): Set it.
	* ldlang.h: Declare lang_default_entry.
	* emultempl/beos.em, emultempl/pe.em: Use lang_default_entry,
	not lang_add_entry, to override default entry point symbol.

ld/testsuite:
	* ld-scripts/align.exp: Mark align1 XFAIL on PECOFF targets.
	* ld-scripts/data.exp: Mark data UNSUPPORTED on a.out targets.
	* ld-scripts/provide.exp, ld-scripts/size.exp: Mark all tests
	UNSUPPORTED on a.out targets.  Tidy.

/* If the subsystem is windows, we use a different entry
point. We also register the entry point as an undefined
symbol. from lang_add_entry() The reason we do
this is so that the user
doesn't have to because they would have to use the -u
switch if they were specifying an entry point other than
_mainCRTStartup. Specifically, if creating a windows
application, entry point _WinMainCRTStartup must be
specified. What I have found for non console
applications (entry not _mainCRTStartup) is that the .obj
that contains mainCRTStartup is brought in since it is
the first encountered in libc.lib and it has other
symbols in it which will be pulled in by the link
process. To avoid this, adding -u with the entry point
name specified forces the correct .obj to be used. We
can avoid making the user do this by always adding the
entry point name as an undefined symbol. */
