* config/abi/pre/gnu.ver (CXXABI_1.3.6): Add symbols.
__cxa_get_exception_ptr is now present in both CXXABI_1.3.1 and
CXXABI_1.3.6, which breaks Solaris bootstrap with Sun ld:
ld: fatal: libstdc++-symbols.ver-sun: 5210: symbol '__cxa_get_exception_ptr' is
already defined in file: libstdc++-symbols.ver-sun: symbol version conflict
The duplicate serves no purpose I can see, and even with both entries,
__cxa_get_exception_ptr is bound to version CXXABI_1.3.1 only on
x86_64-unknown-linux-gnu, so it seems safe to remove.
This restores Solaris bootstrap, tested on i386-pc-solaris2.11.
Ok for mainline?
