>Description:
bsd.README says
       bsd.subdir.mk:
                ...
                There is also a default target which allows the command
                "make subdir" where subdir is any directory listed in
                ${SUBDIR}.

Target <subdir> actually does not work both with
/usr/share/mk/bsd.subdir.mk and /usr/pkg/share/mk/bsd.subdir.mk.

./test5/Makefile
0 mytest>make test5
`test5' is up to date.
0 mytest>make test50
`test50' is up to date.
0 mytest>
==========================================================
I expect that "make test5" should print 5 and "make test50" should print 50 .
