We could just leave it up to the system vendor / installer.
Hello is a gcj built program...
$ LD_DEBUG=libs ./Hello
this results in a bunch of output including...
02327: trying file=/usr/etc/i686/mmx/libm.so.6
02327: trying file=/usr/etc/i686/libm.so.6
02327: trying file=/usr/etc/mmx/libm.so.6
02327: trying file=/usr/etc/libm.so.6
So it seems ld.so already knows to look for special mmx and i686 variants of
libraries on x86 Linux. If ld.so were changed to look for "up"
(uniprocessor) variants then we could just tell system vendors / installers
to configure with --enable-uniprocessor and install the library in the right
place.
