mk: fix external builds with relative output dir

In case the output directory (O=) is undefined or a relative directory lets
turn it into an absolute path before passing it on. Otherwise the output
directory is created relative to the subdir, e.g. pktgen/app/build/... and
pktgen/lib/lua/src/build/...
