Despite that tar is available everywhere, it's not required by POSIX.
And, we're allow users to specify which tar they want to use in Makefile
knobs, and we prefer GNU tar in autotools script.
In our testsuite, 7 out of 9 tar-required-tests use "$TAR", the other
two use "tar".
Let's change the remaining two tests to "$TAR".

I found this when trying to remove tar from a chroot that used to test Git,
such chroot has bsdtar, so I tried to set "TAR = bsdtar" in config.mak

The last part I didn't know about---it is sad if autotools require
use of gtar (but since use of autoconf and autotools is not required
to build Git, I do not deeply care ;-)).

Nice.

Despite that tar is available everywhere, it's not required by POSIX.
In our build system, users are allowed to specify which tar to be used
in Makefile knobs. Furthermore, GNU tar (gtar) is prefered when autotools
is being used.
In our testsuite, 7 out of 9 tar-required-tests use "$TAR", the other
two use "tar".
Let's change the remaining two tests to "$TAR".

I do not care, either. Just want to add more data points for this change.
I've made a grammar error with v1, and I think two "and" in a sentence is not
good enough. Let's take this version instead.
Range-diff against v1:

I don't believe we do require it. macOS ships bsdtar (that is, the one
from libarchive) and to the best of my knowledge, everything works fine
there.
I suspect the reason that gtar is preferred is because on some systems,
the tar(1) command is relatively incapable and doesn't support things
like POSIX tar archives or pax extensions.
