[Buildroot] Target to create missing hashes.

Johan, All,

Well, we do not want the hashes to be automatically created, because we
want them to come from upstream if possible, and only if upstream does
not provide hashes do we locally compute them.

So, we can't offer an automatic way to create hashes. It has to be a
manual process.

Well, I have a series that makes missing hashes a hard error (when the
.hash file exists), so that will be caught fairly easily! ;-) And a
missing .hash file would become a warning for now, with the ultimate
goal of making it a hard error in the future (because we do not have
enough packages with a .hash file for now).

There is the idea floatign around of creating a check-package (or
check-patch) script that could be used to validate a new package, and
checking a .hash file exists could be part of that script.

Any taker? ;-)
