freebsd-src/targets/Makefile
Simon J. Gerraty 312809fe7f Update dirdeps.mk and gendirdeps.mk
The env space consumed by exporting all libc's .meta files
left little room for command line,
so unexport when done.

Update dirdeps.mk to latest and add
dirdeps-targets.mk to simplify/update targets/Makefile

Makefile changes to go with Makefile.depend changes in D22494

Makefile

# $FreeBSD$
# This is the top-level makefile - derived from the Junos version
#
# If a subdir that matches the requested target exists, we assume
# a build target and initialize DIRDEPS, dirdeps.mk does the rest.
#
# Otherwise we include Makefile.xtras and hope it knows what to do.
