mpfr: Fix compilation for ARC
MPFR has a couple of things implemented in assembly and in case of
ARC those parts were written long ago when ARC GCC port was not yet
upstreamed. On upstreaming of GCC some constraints were changed and
so we can no longer build MPFR for ARC with up-to-date tools seeing
something like that:
| In file included from ../../mpfr-4.0.1/src/mpfr-impl.h:112,
| from ../../mpfr-4.0.1/src/mul.c:24:
| ../../mpfr-4.0.1/src/mul.c: In function 'mpfr_mul':
| ../../mpfr-4.0.1/src/mpfr-longlong.h:415:3: error: impossible constraint in 'asm'
| __asm__ ("add.f\t%1, %4, %5\n\tadc\t%0, %2, %3" \
