an in-tree mpfr build enables inline asm code, which makes the mips-bootstrap

because at least mpfr 2.4.2 uses the "=h" constraint but in

supported.".
Using asm code is generally not desirable for in-tree mpfr builds.
Why not?
So I looked for a way
to disable the asm code, and found it can be done, but differently than for
in-tree gmp.
See the attached patch.
Fix mpfr instead not to use that constraint?
