[arch-general] Adding a "posix" metapackage

[Ralph Corderoy]

Hi Ralf,

> Could you please provide a pointer to the start of this thread?

As Eli pointed out, it started on another list to which I can subscribe,
but not post.  On attempting to post, the auto-reply suggests using
arch-general if it's thought important enough, so I did.

Another time, I'll make clear it's a carry-over from a different list to
avoid confusion for those not reading both.
