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.

        There are two versions of linuxthreads.  The older (stable) version
yann@1977
    16
        has been in uClibc for quite a long time but hasn't seen too many
yann@1977
    17
        updates other than bugfixes.

        The new version has not been tested much, and lacks ports for arches
yann@1977
    25
        which glibc does not support (like bfin/frv/etc...), but is based on
yann@1977
    26
        the latest code from glibc, so it may be the only choice for the
yann@1977
    27
        newer ports (like alpha/amd64/64bit arches and hppa).
