Does the build system need any special flags for cpu-targeting?  I.e. 
does the build system detect the cpu that it is building on?  If that's 
the case, I believe we've usually targeted the least common denominator 
for our supported system (e.g. SSE2 for x86-64).

Another option is to do the same as for ATLAS, which is to force a
local build.

With only "make" the CPU is detected as part of the build process.  If
the "TARGET" flag is provided a specific CPU is targeted.

Attached is an updated patch that forces a local build.
