[RFC PATCH] Makefile: new prove target for running the tests with TAP

[Michael J Gruber <git@drmicha.warpmail.net>]

Introduce a new make target "prove" which runs the tests via "prove" (or
$(PROVE) if set) so that one does not have to cd around any more. One
can simply use "make prove" for "make test" or go wild as in:

GIT_SKIP_TESTS='t[0-4]??? t91?? t9200.8' GIT_PROVE_OPTS="-j9 -v" GIT_TEST_OPTS="--verbose --debug" make prove

RFC also because of lack of doc, and:

Currently, one can do

make -C t t6010-merge-base.sh

or even

make -C t t601*

which is cool but undocumented. If we want this with prove it requires more
effort, or shoving prove into the $(T) target rule which is doable, of course.
I'm just wondering whether it's accepted to introduce a specific rule for prove
at all.
