This is OK for now, but I wonder why this is done in test-lib.sh in
the first place, unlike $(TAR) that is set and configurable from the
top level.  The difference is that GIT_UNZIP happens to be used only
in tests, while TAR is used in the primary build procedure.

But I suspect that in the longer run, we should allow UNZIP to be
given next to TAR to the top-level Makefile and export it down.
That would allow the usual mechanism like config.mak.uname,
./configure and "make TAR=... UNZIP=..." command line override
to be used uniformly, without people having to worry about the
distinction.  The builders should *not* have to care that one is
used in the build and the other is only used in the test.
