Oops, sorry, I was thinking of the x86_64-pc-solaris* case, which wasn't
supported prior to GCC 4.7 (PR 39150)

That doesn't change the fact that this PR is clearly this FAQ
http://gcc.gnu.org/wiki/FAQ#configure_suffix and will almost certainly be
solved by using the contrib/download_prerequisites script as suggested at
