"glorious".

Hmm. I _really_ don't love how it now uses that odd label across
macros, it's not screaming "obvious" to me.

How bad would it be to just not use a NULL pointer at all, and instead
make the "no format" be "empty format"?

(Slightly related thing: could we perhaps just make x86-32 also use
the relative format, and get rid of some of the horrid #ifdef's in the
x86 <asm/bug.h> implementation? Because that "__BUG_REL" thing is not
a thing of beauty either).
