The attached patch adds support for the AAPCS ABI (part of the Arm EABI).

This is based on an earlier patch here:
http://sourceware.org/ml/gdb-patches/2004-12/msg00358.html
Which was more-or-less approved, but I only just got round to updating it.

The support for different elf header flags has already been merged separately. 
This patch is the remaining procedure call interface bits. I've also 
addressed the comments in the above mail.

Tested with cross to arm-none-eabi.
Ok?
