Hang up at boot on armv5t

[Warner Losh]

Well, you could do something cheezy like #ifndef arm :)

If you do that in the latest sources, does it solve the problem?

diff --git a/sys/sys/systm.h b/sys/sys/systm.h

 })

 void   explicit_bzero(void * _Nonnull, size_t);

 void   *memcpy(void * _Nonnull to, const void * _Nonnull from, size_t len);

And is this built with gcc or clang? What version?
