[Bug c/45010] New: Link errors in bootstrap with static libgmpxx.a

["marc dot mengel at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The link options link with -lgmpxx, but do not include the required -lstdc++
and -lm options to make that link successful.  This works accidentally if gmp
is built as a shared library, which knows its dependencies at runtime, but if
it is built static, the links fail with a sea of errors about undefined
symbols.

Reprodce by:
configure gmp library with --disable-shared and install /some/where
configure gcc with --with-gmp=/some/where
make bootstrap
