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     Rules.mak: Rearrange appending UCLIBC_EXTRA_CFLAGS to CFLAGS
     6     
     7     UCLIBC_EXTRA_CFLAGS is currently added before the OPTIMIZATION flags
     8     and OPTIMIZATION is chosen to be Os by default. But in OE we pass the optimisation
     9     flags through UCLIBC_EXTRA_CFLAGS but they are not effective since -Os is
    10     specified at last. So we need to change the order of these option flags
