Fabian Homborg a4f55d95d4 Detect GNU make via "--version"
Turns out that `make -pn` actually takes a while - about 300ms on
fish's makefile.

That's quite a bit of time just to throw away the output and use the
exit code.

So we just check for "GNU" in the version string.

It would be nice to just _do_ the completion and fall back on the
BSD-style if it doesn't work, but that is tricky to do with the pipe
to `awk` - the awk expression actually does not fail if `make` does
not print output.

And I don't know enough about awk to change that.
