>Description:

In -current, after the bsdtar backout, we fail in pkgsrc big time due to
bsdtar conditional being wrong in pkgsrc/mk/tools/tools.NetBSD.mk:

.if empty(MACHINE_PLATFORM:MNetBSD-[0-8].*-*)

is used to select /bin/tar as bsdtar - which is not true right now.
However, on netbsd-9 we still have bsdtar as /bin/tar.

I would very much prefer consensus on HEAD before pulling up the very
controversil backout, and also want to have 9.0 and -current use the
same tar.

Unfortunately this is a blocker for our 9.0 RC1, so please let us decide
and act quickly.

>How-To-Repeat:
n/a

>Fix:
Decide changes for bsdtar or agree on permanent backout (and stay with
pax-as-tar).
