Many ports carry a BSD makefile in the files subdirectory, install that
and that makefile does all the internal building.

What you are attempting is not done.

The ports Makefiles are meant to handle major targets (configure, build,
install), not do the low level building.  You should have a separate
makefile in WRKSRC for that.
