Yup, I also had some concerns about its name, I naively thought this would
have been raised earlier... ;-)

Introducing the

Well, it's a kind of mess (no offense)!
- BR_ prefix seems being used mostly for internal toolchain (wrapper) stuff;
- BR2_ prefix: widely used in all Config.in;
- BUILDROOT_ prefix: for things that can be set from the environment;
- PKG_ prefix: in my mind it's to close to what we can set for pkg-config -
I don't really like this one.

Maybe it's time to write down the rules for the prefixes?

Anyway, I'll wait to get more inputs before repost the series.
