I've been encountering the following link errors trying to build a
MONOLITHIC i386 kernel _with_ LOCKDEBUG defined for almost two days now:

I do see what looks to be the appropriate #if !defined(LOCKDEBUG) in
sys/arch/i386/i386/lock_stubs.S, but that doesn't seem to have the
desired effect somehow:
