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.

    24         The new version has not been tested much, and lacks ports for arches
    25         which glibc does not support (like bfin/frv/etc...), but is based on
    26         the latest code from glibc, so it may be the only choice for the
    27         newer ports (like alpha/amd64/64bit arches and hppa).
