why don't Gnulib tests run for me?

[Ben Pfaff]

I finally got back to working on the proposed <math.h> module and
I'm trying to figure how tests in Gnulib work.  In particular,
I'm confused that when I use "gnulib-tool --test <module>", the
tests for the module don't actually seem to run.

This seems to be because the Makefile.am module specification is
not getting propagated to any actual Makefile.am.  For example,
for me, when I run the following:
        ./gnulib-tool --create-testdir --dir=foo arcfour-tests
        grep -r TESTS foo
I get null output, even though the arcfour-tests module contains
the following:
        Makefile.am:
        TESTS += test-arcfour$(EXEEXT)
        check_PROGRAMS += test-arcfour

Any idea what I'm doing wrong?
