The problem is already fixed in r202755 by Ed.  When libulog was first
added, it was needed for libpam (pam_lastlog), so it had to be built
before libpam in Makefile.inc1:_prebuild_libs.  What broke parallel
builds is that Ed forgot to add an inter-library dependency of libulog
on libmd.  Now that libpam no longer required libulog it was removed
from Makefile.inc1 completely, and the problem is resolved.
