If the support programs need to be the same wordsize as the app/libraries
in question, it should be in /usr/{lib,lib64}/<app>.

If they don't care, it can be in /usr/libexec.

For example, xscreensaver has screensaver hacks in
/usr/libexec/xscreensaver - these don't care about the wordsize at all
(in fact, they can be shell/python/etc). So, /usr/libexec seems
appropriate here.

As a counter example of something broken, there is
/usr/libexec/sudo_noexec.so, which really should be in
/usr/{lib,lib64}/sudo.
