[mc1322x] Building mc1322x contiki

[Jon Smirl]

I'm trying to build the mc1322x contiki examples using
gcc-4.3.2-glibc-2.8-binutils-2.18 from the Phytec cross tools.

My binary is ending up 550K. It is sucking in 500K of run-time
library. Are my cross tools built wrong? Should they be built with
exception handling turned off?

I had to add the exidx section...
