Problem here was that GCC-related options are not applied in stage2 (and later

It's caused by fact that CXX is xg++ in stage2 (and later stages).
Fixed with the following patch.
Ready to be installed?

* Makefile.in: In stage2 in UBSAN bootstrap the CXX is called
xg++, so findstring g++ should be used instead of exact string
comparison.
I think better would be to follow gcc/{configure*,Make*} practice and don't
judge compilers based on names, but on what they actually are and test
perhaps not each individual flag separately, but their whole sets together.
Just so you know, it checks the name, because Clang identifies as GCC,
but can be insufficiently GCC-like at times (not here though).
I think replacing more bits with libcpp configure goup is probably the
better.
