freebsd-skq/share/mk/gendirdeps.mk
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
