Include apr-util's LDFLAGS

Using apr-util installed by Macports results in build failure because apr-util uses BerkeleyDB that MacPorts installs into a subdir of $prefix/lib and $prefix/include (so that multiple versions of BerkeleyDB can be installed simultaneously). apu-1-config's --ldflags output includes the -L/path/to/bdb that's needed.
