[mc1322x] building on a mac

[Andrew Pullin]

You should test something that uses floats, sqrt() and/or cos(), -lm, 
and -static , and see if it all works out, and what size the final ELF is.
I haven't got working gcc with newlib, soft-float, interworking, and the 
libmc1322x code working yet, but I'm learning a lot about GCC trying to 
do so.
