HAVE_KPRINTF_ATTRIBUTE would get defined when built from the NetBSD
source tree with the kprintf attribute patch.  The kprintf attribute
patch adds a new attribute `kprintf', that's like `printf', but also
understands some other formats available in the NetBSD kernel printf.
It's used to have printf format checking in the NetBSD kernel.

...because it requires an extension to the compiler, which has
not beed contributed back since is changes MI compiler code but
is NetBSD-specific.

Even in ELF they are broken.  But I think I know why, and I'll chat
with Matt out-of-band about this.
