Attached is a patch against apr-util that solves the problem without
touching the defaults. It allows building against expat residing in
lib64 for 64bit installations by specifying "--enable-lib64" to
configure as well as expat residing in lib for 32bit installations.
The neat thing is that "--enable-lib64" is generic and its value can be
reused whereever the same problem arises.
