For the 'havelib' tests, it is necessary for the module to know the location
of the macros in the tarball. This provides it, through a shell variable at
configure time. Its use is generally not recommended, but in cases like this
one, I don't see how to avoid it.

        gnulib-tool: Provide the value of --m4-base to modules.
        * gnulib-tool (func_import, func_create_testdir): Emit a definition
        of gl_m4_base.
