gmpxx.h is part of the GMP source distribution, it's not generated

Not really, if you don't say which versions of GCC and GMP/MFPR/MPC you're
using, and your exact configure command, then it's not reproducable or
verifiable.

It also seems to be completely unrelated to this bug report, which is about
segfaults (almost certainly due to faulty hardware) not incorrectly-detected
system properties during configuration.
