bdrewery d7fe1b3fea bsd.subdir.mk: Move all of the targets into ALL_SUBDIR_TARGETS.
Also improve documentation.

The SUBDIR_TARGETS variable should really be named LOCAL_SUBDIR_TARGETS, but
renaming it may be a surprise for downstream vendors who use this variable.

# $FreeBSD$
#
# 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".
#
# See ALL_SUBDIR_TARGETS for list of targets that will recurse.
# Custom targets can be added to SUBDIR_TARGETS in src.conf.
