Then please do use "make -jN bootstrap", where N is the number of
execution units you have on that system.  That's how you request
parallel Emacs builds.

The way we natively-compile Lisp files during a build was
intentionally made serial, so that the Make command could control how
much parallelism is in use.  Because otherwise, we could easily
overwhelm the CPU, because the inherent built-in parallelism of the
async native-compilation doesn't care about the system load, so
invoking "make -j8" would give you 8 compilation jobs, each one of
which could use 4 cores.
