2011-02-14bfd/ld: handle ABI prefixes in version scriptsMike Frysinger1-5/+17
The default language in version scripts is supposed to be C, but no symbol demangling is performed on the symbols by default. This makes targets with a symbol prefix to fail with most version scripts out there. So strip away this prefix by default. This fixes many tests (real world and ld's testsuite) for Blackfin targets and doesn't seem to cause regressions for x86_64. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
