[PATCH] Added a baremetal ARM Cortex-M3 sample that uses the latest Linaro


# HG changeset patch
# User Michael Hope <michael.hope@linaro.org>
# Date 1317178947 -46800
# Node ID ccba0d4551b2735d29413a4a1b24af37358ebaf7
# Parent  8787c0fd1b726a336314e3a29db4ebe9ef73c8ad
Added a baremetal ARM Cortex-M3 sample that uses the latest Linaro
consolidation releases.  Just to push the envelope, it also uses the
latest companion libraries, binutils, and Newlib.

Normalised against the arm-unknown-eabi sample where possible.

Uses getconf to automatically set the number of parallel jobs.
