cc/gcc: do not force use of non-vital companion libraries

Browse Source 
While GMP and MPFR are required by gcc>=4.3 (to build the frontends),
and MPC is required by gcc>=4.5, the other libs are not. If they are
present then gcc will enable advanced features; if they are missing,
then gcc will (should) simply disable those features.

Enable the GRAPHITE loop optimsations.
This requires the PPL and CLooG companion libraries, and
those will be automatically build for you.
On some systems (eg. Cygwin), PPL and/or CLooG may not
build properly (yet), so you'll have to say 'N' here.
