Warner Losh e0be2e9bc8 Automatically append SUBDIR.yes to the SUBDIR variable, and
remove duplicates. We cannot sort SUBDIR because many Makefiles
have .WAIT in the list which is strongly ordering. Rather than
try to second guess when to sort and when to not sort depending
on .WAIT being in the list, just remove duplicates.

# from: @(#)bsd.subdir.mk 5.9 (Berkeley) 2/1/91
# $FreeBSD$
#
# The include file <bsd.subdir.mk> contains the default targets
# for building subdirectories.
#
# For all of the directories listed in the variable SUBDIRS, the
# specified directory will be visited and the target made. There is
# also a default target which allows the command "make subdir" where
# subdir is any directory listed in the variable SUBDIRS.
#
#
# +++ variables +++
#
# DISTRIBUTION Name of distribution. [base]
#
# SUBDIR A list of subdirectories that should be built as well.
# Each of the targets will execute the same target in the
# subdirectories. SUBDIR.yes is automatically appeneded
# to this list.
#
# +++ targets +++
#
# distribute:
# This is a variant of install, which will
# put the stuff into the right "distribution".
#
# afterinstall, all, all-man, beforeinstall, checkdpadd, clean,
# cleandepend, cleandir, cleanilinks depend, install, lint,
# maninstall, manlint, obj, objlink, realinstall, regress, tags
