META_MODE is only allowed in a whitelist of targets (see
META_TGT_WHITELIST in Makefile).  I wanted to avoid META MODE ever being
enabled for an 'install' target or utility target like 'check-old' or
'delete-old', etc.  META MODE has the potential to skip doing things
that are actually needed, like copying a file to /.  So I decided to
whitelist to known-safe targets.  The 'make release' target, and all of
release/, is something I've never ran and am not very familiar with, so
I didn't list it.  Thus WITH_META_MODE=yes and 'make release' has no
effect, it will build without META MODE.

In summary, support needs to be added for release/ in safe and useful ways.
