The root Makefile does not hook into lib/ via <bsd.subdir.mk> since it
is not a program itself and thus gets included by all others.
 
This means `make tags` skips lib/ and `make -C lib/ tags` does not know
what to do;  provide a minimal <bsd.prog.mk> stub and hook it up just
or the "tags" such that *all* source is browsable via tags.
