current testresults, x86/linux are quite poor

[Benjamin Kosnik <bkoz at redhat dot com>]

... help! I've just switched out my underlying hardware platform due to
finally toasting my notebook.

As I get back into it, I am seeing these testresults on FC6 with
today's gcc:

Ouch!!!!! Anything I should know? Paolo, are you seeing this too?

Debugging, I see:

Jeeze. What happend? I see gcc-regression also is useless, an extension
of the gmp flamewar.

Looks like the codesourcery tester was fine yesterday:
