No, I'm talking about a fresh build, or bootstrap, or a build after
all the *.elc files have been deleted.

The only single-threaded parts I see is (a) the configure script (and
autogen.sh, if that needs to be run), and (b) the link stage of the
Emacs executable.  Everything else runs in parallel, and if I says
"make -j8" I see load-average show numbers around 8 most of the time
on the mode line.
