We didn't prefix any of our submake $(MAKE) invocations with +, so the
jobserver couldn't be used.
This also (so far?) seems to fix some problems I had with "make -j16"
(or anything higher than -j4) breaking due to some vrclient/steamclient
linkage problems.

The main "proton" script tries to compare the version file in DST_BASE
with the one in DST_DIR, but the one in DST_BASE was missing, causing it
to fail to run anything.
