You are best off just using --enable-proc-opt. I think that there is
something wrong with the way configure determines the architecture
although I cannot see what it does wrong. I used --arch=i686 on my Intel
Core 2 Duo motherboard, and then noticed that make was using
'-march=k6'!....I added the cpu_type 'core2' to the enumerated types in
configure at about line 700, and it then ran nicely.
Minutes later, configure on my Intel Pentium4 desktop choked on
--arch=permtium4 and I had to revert to --enable-proc-opt...
I have NO idea why or what!
