gcc/mpfr: Disable LTO unconditionally.

This is kind of a hack, but really it's the configure script that
is broken, as it hard-checks for "gcc-ar" which of course does not
work with Clang builds. We want LTO to be enabled in GCC, and
GCC unconditionally passes all arguments it gets to sub-configures,
so all we can do is stop the flag from having any effect.

Fixes #14733.
