OK, that's fine.  I'll compile without any of the fancy vector
instructions for i686, then explicitly pass an -march arg of my own (I
see some other packages use -march=pentium4) for the version that will
live in /usr/lib/sse2.  For x86_64, I'll make sure that SSE3 and SSSE3
support is off and let it do its thing otherwise.

Thanks, Ajax!
