The distinction between stuff which belongs into %{_libdir}, which is 
different for 32-bit vs. 64-bit, vs. stuff which always goes to the same 
place and where only one copy should be installed.

Now it's possible to hardcode /usr/lib (and some stuff notoriously does 
this), but IMHO this is all broken. Everything installed by an x86_64 RPM 
into /usr/lib is in the wrong place. It should be in /usr/libexec, 
/usr/share, /usr/bin or /usr/lib64.
