Oh yeah, libraries... there is also a LOCAL_LIB_DIRS you can set to
list libraries.  But looking at Makefile.inc1 it builds the local lib
dirs after the other local dirs, which seems completely wrong and
useless.  I think the LOCAL_LIB_DIRS should be built along with the
base system dirs; the attached patch would do that.
