Log Message:
lang/go126: Avoid excessive parallism

Tell "go build" to use at most ${MAKE_JOBS} threads, instead of the
vastly higher number that it tends to use, at least on machines with
many CPUs.  This meets the intent of MAKE_JOBS because there is only
one "go build" process.

As discussed on tech-pkg@ with no $MAINTAINER objection.
