What you've documented above is the Correct Way(tm) to remove lib32
support.  Though I advocate people not install it in the first place,
unless they absolutely need it.

The message from /etc/rc.d/ldconfig you see there about 32-bit
compatibility ldconfig path is fine -- it shows an empty path, which is
correct.  Nothing to worry about there.

My systems, which have never had lib32 ever, show the same:

ELF ldconfig path: /lib /usr/lib /usr/lib/compat /usr/local/lib /usr/local/lib/mysql
32-bit compatibility ldconfig path:
