FWIW I'd also appreciate to have an option to easily parallelize builds
without having to call make separately.

We're now at a point where it doesn't seem very exotic to have 12-16
cores in an affordable, portable 14" laptop[1], so IMHO it should be as
easy as possible to utilize those, as it does make things a lot faster.

Maybe it should even default to the number of available cores (i.e.
"nproc")? Though others might prefer using a single job by default like
make does as well, not sure.
