HardenedBSD/share/zoneinfo/Makefile
Simon J. Gerraty 0a45a7e99f Fix share/zoneinfo for DIRDEPS_BUILD
The tranditional build makes multiple passes through the tree.
The DIRDEPS_BUILD visits each directory only once per architecture,
thus makefiles should be able to everything they need in a single pass.

The use of TZS!= when doing make(*install*)
only works if the directory has previously been visited to do zoneinfo
since before the zoneinfo target is run TZS will be empty.

To fix this, have the zoneinfo target capture the list of files to
zoneinfo, and install-zoneinfo use that list.
Rename that target to zonefiles - since that is now what it does.

This is more efficient - we only gather the list of zones when it is
likely to have changed, and allows the makefile to do everything in a
single pass.

# HOW TO UPDATE THE ZONEINFO DATA
#
# Import the new sources to the vendor branch:
#
# $ cd ~/freebsd/src
# $ git worktree add ../tzdata vendor/tzdata
# $ pushd ../tzdata
# $ tar -xvf ../tzdata-latest.tar.gz
# (check with "git status" and "git diff" if it all makes sense)
# $ git add -A
# $ git commit -m "Import tzdata 20XXX"
# $ git tag -a -m "Tag import of tzdata 20XXX" vendor/tzdata/tzdata20XXX
# $ git push --follow-tags freebsd vendor/tzdata
# $ popd
#
# Merge-from-vendor
#
# $ git subtree merge -P contrib/tzdata vendor/tzdata
# (write a meaningful commit message)
# $ git push freebsd HEAD:main
#
# MFC
#
# $ git checkout -b freebsd/stable/12 stable-12
# $ git cherry-pick -x [hash of merge commit to main] -m 1 --edit
# (write a meaningful commit message)
# $ git push freebsd HEAD:stable/12
#
#
# If there are changes to zone1970.tab, update the baseline file by running
# `make baseline` in usr.sbin/tzsetup to check if tzsetup is able to parse new
# contents (if not, report/fix tzsetup). Check that update does not
# introduce breaking/unexpected changes to continents/countries/zones,
# and commit the updated baseline file.
