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.

reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g.,

     4
MPC8548, MPC8572).  It uses eglibc (for e500/SPE patches) and a recent
yann@935
     5
gcc (4.3.1, for e500v2 DPFP support) and will generate appropriate

dual-precision floating point instructions by default.

Note: If building a Linux kernel with this toolchain, you will want to

make sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE

    10
ABI/instructions from getting into the kernel (which is currently
yann@935
    11
unsupported).  At this time, the kernel build system only passes

    12
-mno-spe by default (this should be fixed soon hopefully)."
