AMD's Family 6 CPUs come with two flavors: one that supports SSE and

one that dosen't. However, they're not easily distinguishible from
their signature (family, model and stepping). Original configure might
set -march=athlon-4 for a CPU that dosen't support SSE and causes gcc
to generate code that won't run on the target machine.
Closes bug #267.
