cc/gcc: build core compilers for canadian

Currently, we rely on an existing external cross-compiler targetting
the target, to build the C library.

This can pause quite a few problems if that compiler is different from
the one we are building, because it could introduce some ABI issues.

This patch removes this dependency, by building the core compilers
as we do for standard cross, and also by building the binutils and
gcc, for running on the build machine.

This means we no longer need to offer the cross-sompiler selection in
the menuconfig.

     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
