That would be my guess.  Looking at the buildbot log, neither rx.o or
rx_globals.o are rebuilt during the failed build.  So we probably have
an rx_globals.o that dates from before that change, while rx.o was
rebuilt after the change.

The kernel makefiles dont't have very detailed dependencies, so they
don't catch that rx_globals.o needs to be rebuilt in this case because
of the cahnge in rx_globals.h.
