Hi,

This commit makes pkg angry when trying to use zstd support -- I
tracked it down to libarchive wanting to shell out now, because this
conditional changed:

https://cgit.freebsd.org/src/tree/contrib/libarchive/libarchive/archive_write_add_filter_zstd.c#n112

We should probably make pkg accept ARCHIVE_WARN since shelling out
isn't so bad, but I have this diff to fix base libarchive:

https://people.freebsd.org/~kevans/libarchive.diff

I didn't quite check if there were any other surprises like this,
though. Is this sufficient and OK to commit?

Thanks,

Kyle Evans
