Since the -lrt appeared in the second phase, it is probably being picked
up from a .la file somewhere.  For each .so listed in the second phase,
check whether the accompanying .la exists and contains a -lrt (e.g.
/lib/ -> /lib/  If so, rename/move/delete the .la file and rerun
make.  These .la files are generally useful; but they sometimes contain
bad information.
