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.

     5 Set the default behavior on alpha to use -mieee since the large majority of
     6 time we want this (bad/weird things can happen with packages built without
     7 -mieee).
     8 
     9 To satisfy those people who may not want -mieee forced on them all the time,
    10 we also provide -mno-ieee.
