Simplify last commit by only calling cat once (this should hopefully resolve

rbb's concern about maintainability and still address mine about annoying /s).

Don't call mkdir when we are the top-level directory.  We *have* to have
been created before hand.

Also add this fix to the bsd_makefile section.
