Joshk told me that sparc32 muldiv is currently ignored to search
/usr/lib/muldiv, and this patch should fix that problem.
But in sarge, Ben Collins decided to drop old sparc which does not
support hardware muldiv. It means this proposed patch is
automatically unusable. I don't know this patch makes sense even if
debian does not support hardware muldiv.
