This is normal. The --extract* accessors give low-level access to the
module description, so that anyone can experiment with new ways of using
or verifying the module descriptions. However, there is some magic that
currently is handled inside gnulib-tool, such as the dependencies, the
GPL->LGPL conversion, the EARLY stuff.

I'm committing the appended change, so that you won't fall into the same
error again. However, there is still a problem with LIBOBJ in this case.
People using --makefile-name now must define AUTOMAKE_OPTIONS themselves
and provide initial definitions for EXTRA_DIST, MOSTLYCLEANFILES etc.
themselves. This is a little more manual work, but allows the generated
gnulib.mk to be fully incremental. One might consider to write out
the set of empty variable assignments to a separate file, but for the
moment I'd consider such a feature as bloat.
