Maybe "make -jN" with N too high causes some issues with time stamps?
Otherwise I don't understand how this could happen: the emacs
executable depends on all the preloaded *.elc files, so recompiling
any of them should re-dump Emacs.

You need to delete the emacs executable as well, and touch temacs.
