end of link. Basic order is:
$LDFLAGS internal-libs external-libs $LIBS $LTHREAD_LIBS
LTHREAD_LIBS is last as -lpthread (or equiv) must be last on many systems.
LIBS is next to last as some user might have put -lpthread (or equiv)
in $LIBS.
make depend, make tests, and make install all work when build directory
is not the $srcdir.
Also modified library handling such that -lpthread more likely to be last.
WARNING: new orderring requires use of LDFLAGS to set global loader options
such as -L/usr/local/lib. If you put this in LIBS, some libraries
may not be found a link time.
Likely broke Kerberos/LDAPD support. Don't have those in my testbed.
