There is a big gap/leap between these two sentences. The first
sentence might justify TAR_XF but it does not explain why TAR_CF
is needed at all. Also there is "$(TAR) czf" that is left without
getting turned into $(TAR_CF)z.
Are there still remaining uses of $(TAR) after applying this patch?
If with a different justification, a patch that abstracts our use of
"tar" as an archiving tool into different use cases and give one
Makefile macro to each of them with more meaningful names might be
more palatable. E.g. instead of TAR_CF that abstracts only the "tar
cf" part, make "take everything in the current directory and send an
archive of it to the standard output", i.e. "tar cf - .", into a
Makefile macro, with matching "take an archive from the standard
input and extract it to the current directory", i.e. "tar xf -", as
a matching Makefile macro, perhaps---that way people without a
working "tar" might be able to use zip, cpio or pax (or a script
written around them) as an alternative "archiving tool", for
example.
Side note. The above would probably be a huge undertaking
and I am not suggesting it as a serious counterproposal.
A more plausible alternative is to just touch "$(TAR) xof -" and
replace it with $(TAR_XOF) or even $(EXTRACT_TARBALL_AS_MYSELF)
while leaving $(TAR_CF) alone. That _might_ be palatable.
I dunno.
