I think perl is necessary for the test suite, but not for git-mergetool
itself. And this is a problem in the script itself, IIRC; so it really
is broken on your system (albeit in a really tiny way), and not just a
test portability thing.
So the viable solutions to me are one of:
1. Accept that this little part of mergetool doesn't work on systems
without "mktemp", make sure we fail gracefully (we seem to), and make
sure the test suite can handle this case (which was the earlier
patch, I think).
2. Implement our own git-mktemp (or similar abstraction) in C. We
already have all the code, so it really is just a thin wrapper.
I don't mind (2), but given the lack of people clamoring for a fix to
mergetool itself, I'm perfectly happy with (1).
