explicit_bzero(Linux 3) -> explicit_memset(3)

For example xorg libXau (I'm working on debugging X11 stuff; this is
why...) uses explicit_bzero(Linux 3) that NetBSD does not provide
(legitimately: bzero(3) has been deprecated in POSIX since there is
memset(3)).

But there is explicit_memset(3) to avoid compiler optimizing the
zeroing away.

Is there some policy concerning this, i.e. mapping explicit_bzero(3)
to explicit_memset(3) in external code? (I could also propose a patch
upstream to have a feature macro to use explicit_memset(3) when
available).
