Why does adding /usr/lib32 to LD_LIBRARY_PATH break 64-bit binaries?

I maintain that rtld should not load 32-bit libraries for a 64-bit
binary. That is WRONG anyway you look at it.  And again, if it checked
the arch type and skipped libutil.so.5 in /usr/lib32 it would fall
back to checking /lib and things would work.  Moreover, if /usr/lib
had major number links just like /usr/lib32 has, this would again have
worked without issue.

I believe this will be fixed on the other side of the fence (not
setting LD_LIBRARY_PATH to include /usr/lib32 to begin wtih) but
still, my point still stands.
