bug in mathl module

[Bruno Haible]

$ gnulib-tool --create-testdir --dir=testdir mathl
...
executing autoreconf --force --install
lib/Makefile.am:28: noinst_HEADERS must be set with `=' before using `+='
autoreconf: automake failed with exit status: 1

Should the module description use EXTRA_DIST instead of noinst_HEADERS?
Well, noinst_HEADERS explains more precisely the purpose of the files. So
I'm changing gnulib-tool:

        * gnulib-tool (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am):
        Initialize also noinst_HEADERS to empty.
