[oe] RFC: madwifi-ng patch rationalisation and version update

[Stelios Koroneos]

The problem originally was created as i used an older version of
madwifi-ng_r.inc to make the updates.
We managed to resolve it thanks to the help of rwhitby.

One the the things that came out of this,was that several packages contain
arch specific definitions and patches that get applied by default, whether
the package gets build for that specific architecture/machine or not.
In many circumstances this is not noticable, in others (like this) is.
Since support for more architectures/machines is happing we need to have a
more close look on this or we will end up with a lot unhappy situations.
