arch: add softfp support

Some architectures support a mixed hard/soft floating point, where
the compiler emits hardware floating point instructions, but passes
the operands in core (aka integer) registers.

For example, ARM supports this mode (to come in the next changeset).

Add support for softfp cross compilers to the GCC and GLIBC
configuration. Needed for Ubuntu and other distros that are softfp.

     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
