I have seen the same problem, which occurred after the most recent
import from gnulib. This is because nt/gnulib.mk needs to be regenerated
from lib/gnulib.mk (to use an extra gnulib module), but the build
machinery does not seem to handle that properly.

To fix the problem:
 - delete nt/gnulib.mk
 - run autogen.sh
 - build as normal
