Upstream problem with most of 4.x line it seems.
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39398
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32581

I'm making a unified gcc spell anyway for my own use and plan on
allowing to pick all languages and even what make target:
all
bootstrap
bootstrap-lean
profiledbootstrap
profiledbootstrap-lean

So it's easy to avoid any such issues.

For gmp and mpfr gcc docs specify one can include the sources into the
tree and gcc will roll it's own. As mpfr seems to be only used by it I
don't see a problem with that and as gmp is needed by gcc as well might
as well include it. Of course any dependency on gmp would then change to
config_query_option.
