* Makefile.in: Generate files list, when supported by the module.

Passes a temporary directory to the $(PKG)_BUILD macro, intended to be
used as a DESTDIR during installation. When the directory is created
by the build step, a files list is generated and the files or copied
over to the real installation directory.
