[PATCH 1/1 RFC - Denzil] nativesdk.bbclass: Fix the remapping code on nativesdk

[PATCH 1/1 RFC - Denzil] nativesdk.bbclass: Fix the remapping code on nativesdk

[Mark Hatle]

The following patch is being sent to the oe-core list in order to meet our
Yocto Project compliance requirements.  We don't believe this patch is
generally applicable to Denzil.

The purpose of this change is to fix the way automatic dependencies and such
are generated when creating nativesdk packages.  (This approach was
abandoned in the Danny development and replaced with the multilib approach.)

---

When remapping the nativesdk we need to change the values of
PACKAGES, as well as the various R* items.  But not only the
values, but we need to rename the vars to their new PACKAGES
entries.

In addition, if a package has "-nativesdk" already in the name
we want to add it to RPROVIDES to avoid compatibility problems.
