Uh oh.  That's bad.  Maybe it wasn't such a good idea to switch
libexecdir from /usr/lib to /usr/libexec?  It breaks applications
using relative paths to search other application components when
run from /bin.

Either we revert libexecdir to /usr/lib, or we will need to add an
automount point /libexec -> /usr/libexec as for /bin and /lib.
