gcc-crosssdk: ignore MULTILIB_VARIANTS in signature computation

The gcc_multilib_setup function is a function that is run at the
do_configure step, so it's counted into the signature computation.
The MULTILIB_VARIANTS this function uses is also extracted to be
taken into consideration. After the change of setting MULTILIB_VARIANTS
explictly vardeps on MULTILIBS, the change of MULTILIBS changes the
signature, thus causing rebuilding. However, in case of gcc-crosssdk,
the setting of multilib should have no effect on it, as it's used
to build nativesdk packages, not the target packages. So ignore
MULTILIB_VARIANTS in signature computation. This fixes oe-selftest
case sstatetests.SStateHashSameSigs2.test_sstate_nativesdk_samesigs_multilib.
