Tito is using broken kernel headers that pollute the namespace with every
CONFIG_ symbol in the kernel, and this clashes with busybox's CONFIG_TR
and CONFIG_WATCHDOG, causing applets.h to barf if they're not switched
on (since the broken headers don't affect kconfig or the makefiles).

Since such broken kernel headers are common enough to crop up every few
months, a simple work around is to move TR and WATCHDOG from CONFIG_
to ENABLE_ early.
