Hi Ross,

Thanks for the review.

You're right, the user of the .pc file should be the origin of the
pkgconf dependency, and removing the emission entirely is heavy-handed.

I've dropped patch 08 and instead added /usr/bin/pkg-config alongside
the existing pkgconfig in RPROVIDES:

   RPROVIDES:${PN} += "pkgconfig /usr/bin/pkg-config"

This satisfies the auto-generated Requires from pkgconfigdeps.sh
without modifying the upstream rpm script.

I also had to remove /usr/bin/pkg-config from nativesdk-sdk-provides-dummy
because RPM 6's internal dependency generator auto-detects file-level
Provides from installed files nativesdk-pkgconf already provides
/usr/bin/pkg-config via the wrapper script it installs, so the dummy
entry caused a conflict.

Will send v14 with this change
