avr32-*-gdb requires modifying gdb.inc / gdb-cross.inc

[Geoffrey Wossum <geoffrey@pager.net>]

Hi all,

I currently have a BitBake recipe that can build gdb 6.4 for the AVR32, and 
I'm about to make one that can build the gdb 6.7 using Atmel's newly released 
patches for the AVR32.

According to this page, http://avr32linux.org/twiki/bin/view/Main/GDBPatches, 
you must do some extra steps to build gdb if you patch it.  My experience 
with Atmel's gdb 6.4 release was that even though they claim you don't have 
to do these steps if you use the full source tarball, you have to anyway.

This requires modifying gdb.inc / gdb-cross.inc.  I think the modifications 
are safe for all platforms, but I was hoping someone could comment before I 
roll a patchset to submit.  

TIA,
---
Geoffrey
