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.

     9 Hi Robert,

    10 

    11 I've attached two patches:

    12 

    13 1/  For crosstool-0.31 which changes the CYGWIN_URL to one which has the

    14 cygwin source archives.  The version of cygwin that is used to build the

    15 cross toolchain has been changed to cygwin-1.5.15-1-src.tar.bz2 since

    16 most of the mirror sites don't seem to have the original archive used.

    17 [created gcc-3.3.2-cygwin-1.5.15-1.dat - dank]

    18 

    19 

    20 2/ The later cygwin source archive fails to cross build with the error:

    21 /opt/crosstool/i686-pc-cygwin/gcc-3.3.2-cygwin-1.5.15-1/lib/gcc-lib/i686-pc-cygwin/bin/ld:

    22 cannot find -luser32

    23 

    24 unless the second patch is applied,

    25
