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

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.

    11       gcc is the full-blown GNU compiler. This is what most people will choose.

    12       

    13       gcc supports many languages, a powerful code parser, optimised binary

    14       output, and lots of other features.
