[mc1322x] Building mc1322x contiki

[Umberto Manzoli]

Are you using a compiler for creating an executable onto a bare-metal
device, or a cross-compiler to create an application to be run into a
(uc)linux system running onto an arm7 machine?
I would suggest you to try some ready-to-use arm-none-eabi-gcc compiler
before completely rebuilding the toolchain, in order to check if it is a
problem of linker script or wrong compiler options.
