Re: [Ltib] CodeSourcery 2010.09-55 toolchain update

[Matt Wilbur]

I've built their stuff from their free tarballs, but it is not fun, and as 
Stuart says, very easy to mess up.  Best thing would be to get the go ahead 
from CodeSourcery, but since Mentor and their team of lawyers snagged them in 
May, who knows how long it would take.

I usually just grab the rpm / tar.gz myself and configure ltib to use a custom 
toolchain in these situations.
