cc/gcc: baremetal requires a two-pass process

Here, we implement a highly ugly hack. I'm not proud of that one...

To build the libstdc++ library, the compiler requires the C library. In
case we build for non-baremetal, this is normally handled by the final
step, later.

But in the case of bare-metal, we never go through the final step (because
it does not work, and it seems complex enough to make it work), so the
baremetal compilers are issued out of the core step.

     3 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

     5 gcc (4.3.1, for e500v2 DPFP support) and will generate appropriate

     6 dual-precision floating point instructions by default.

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

     9 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

    11 unsupported).  At this time, the kernel build system only passes

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