Bug Description
Heya
the livefs buildds can't run the binaries generated by gcc-4.4 on lpia at the moment; it seems they are some early opterons.
What we wanted for karmic was to target mostly lpia CPUs in the lpia toolchain, notably via -Os, but keeping compat with older netbooks such as celeron.
So we should at least disable sse3/ssse3 or go down to some lower arch and tune for atom.
Thanks

hmm, Michael did enable -march=core2 in the lpia-wrapper (which does the same). So what are the minimum cpu features required for lpia?
