create bootstrap version of erlang.mk (ref #187)

By adding a forced req to a erlang.mk target, we make sure that make
will always remake the erlang.mk file, and start over when we have the
updated file in place.

From [3.5 How Makefiles are remade](https://www.gnu.org/software/make/manual/html_node/Remaking-Makefiles.html#Remaking-Makefiles)

    After all makefiles have been checked, if any have actually been
    changed, make starts with a clean slate and reads all the
    makefiles over again.
