libgcc symbol version fixes

- Subject: libgcc symbol version fixes
This patch, previously posted in another thread at
<http://gcc.gnu.org/ml/gcc-patches/2010-03/msg01025.html>, adds a
target-independent definition of the GCC_4.5.0 symbol version, and puts
the previously missing __unordxf2 and __unordtf2 symbols there. (The
target-specific files already providing versions for these symbols also
use %exclude for them, so the versions on such targets are unaffected.)
Bootstrapped with no regressions on x86_64-unknown-linux-gnu. OK to
commit?
