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.

     1 we kind of screwed ourselves into a corner by having the clock symbols

     2 exported only with the glibc-2.0 version ... this patch fixes the

     3 export so all new binaries built against librt will use the correct

     4 glibc-2.2 symbol version

     5 

     6 one day, we'll just drop this on the floor (maybe after 2006.1)
