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.

     7 GCC 4.3 changed the location of some of the header files.  I don't
     8 understand why you'd be getting these errors while building GCC since
     9 it provides them.
    10 
    11 With regard to GLIBC, Roland checked in some changes so that the GLIBC
    12 build system could find the new locations of the GCC provided header
    13 files.
