NetBSD/share/mk/bsd.subdir.mk
tv 1129ed4afe Improve readability and reduce redundant redundancy in share/mk; add some
descriptive comments.  The guts of hostprog, lib, and prog are mostly
unchanged; this will be done in another pass.

Make several things work properly with UNPRIVILEGED set, and make the
install-time "cmp" logic work for MANZ.  Also reimplement INCS{DIR,NAME}_foo
(requested by wiz) in a backwards compatible way.
