sounds good in theory ... but i dont really like the name ;)

maybe something like CONFIG_DEBUG_USE_BB_FUNCS

no need to force error on the warnings ... trust me when i say that if busybox 
emits a warning, we've reviewed the code a few times to try an eliminate 
it ;)
running `make -s` helps a lot with this

ive committed the malloc->xmalloc changes since those are obvious bugfixes but 
the way we implement this check system needs to be tossed around a bit i 

also, i have no idea, but i think the convention is to include busybox.h and 
not libbb.h ?  if so, we can easily enforce that by doing something like:
#ifndef _BB_INTERNAL_H_
# error "don't include libbb.h directly, use busybox.h"
