ld:

	* 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.
