If you're right it will be due to a race in the makefiles.

Since it is a race it will be difficult for other people to
reproduce.  The make output ought to make it clear though.

Try, starting with a clean tree, running this
  (make -j4; make -j4 modules modules_install; make install) 2>&1 | tee ../log
and check that the resulting kernel does fail, and then provide us
with "log".

Then it is unlikely to get fixed any time soon.
