[PATCH] cortex-m0 support

- Subject: [PATCH] cortex-m0 support
Hi,
the following small patch adds support for the ARM Cortex-M0
processor, as a behavior clone of Cortex-M1.
This is the gcc counterpart of the binutils patch submitted in
http://sourceware.org/ml/binutils/2009-03/msg00373.html
If approved, please commit it for me since I don't have write access.
Thanks,
Daniel.
