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.
