Doing a buildworld WITHOUT_LIB32 still creates these dirs. I reported
it a while back but it is still on someones todo list. Not sure if that
is also related to freebsd-update or is the cause of it triggering the
lib32 install.

No they aren't needed, you can delete /usr/lib32 without any problems.
I have been deleting it for a few years now without issue. In fact
deleting it may fix some port builds, such as older versions of
valgrind tested for lib32 to determine if it builds 32bit libs and
failed if lib32 was empty, the new version now has an option for 32bit.
I just keep `rm -R /usr/lib32` as a step in my notes on updating.
