It might be worth checking what MPFR is linking with in the test suite.
I seemed to see it
linking with the system libs when built in tree, rather than the in tree
ones.
This seems a regression in the MPFR test suite compared with 3.1.6

I've given it a try with that combo on sparc-sun-solaris2.10 (a primary

* The gmp reuse test enters an infinite loop on 32-bit sparc.
* The mpfr trint test FAILs on sparcv9. The failure vanishes with
--disable-thread-safe.
* Many mpfr tests FAIL on amd64. Again, they vanish with

I have not yet tried building gcc with those versions yet.
Beside, IMO we need to make sure that trunk and all open branches can be
built with that version set; having to maintain two different sets isn't
an option.
