On a related topic, I wonder if we should add a "-j" parameter if we
build BaseTools for users (e.g. "make -j4 -C BaseTools")? I've found
that it can be pretty slow without it: on my system adding -j4 reduces
build time from 55 seconds to 15. Going higher doesn't seem to produce
much more benefit: -j32 (on a ThreadRipper system) reduces it to 12 seconds.
