Subject: [PATCH] Portability tweaks for LTO tests.
ld/testsuite/ChangeLog:
2011-02-20 Dave Korn <...
* ld-plugin/lto-10r.d: Allow optional underscore prefixes when
checking for known symbol name.
* ld-plugin/lto-3r.d: Likewise.
* ld-plugin/lto-5r.d: Likewise.
* ld-plugin/lto-6.c: Handle non-standard etext name on Windows.
* ld-plugin/lto.exp: Add $gcc_ld_flag carrying -B option to ld under
test when invoking $CC directly rather than via lib support routines.
