[Buildroot] svn commit: trunk/buildroot/toolchain/gcc/4.2.1: avr32_patches_break_x86

[Thiago A. Corrêa]

It was a source download, I suspect the behavior might still be in
there, I haven't tried yet. I was focusing on figuring out in which
revision things got broken... unfortunally it takes over an hour to
try each revision. It was a download from the same repository as the
Atmel's ARM stuff, so, I guess it's now at www.at91.com ftp
