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.
