I've given it a try with that combo on sparc-sun-solaris2.10 (a primary
target) and i386-pc-solaris2.10 (32 and 64-bit each), with mixed results:

* 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
  --disable-thread-safe.

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.
