1) How can user check on target if his package was built with foo enabled?
- is there some plan to keep this in ipk/deb metadata?
2) Is it possible to force some PACKAGECONFIG enable/disabled from
DEPENDS/RDEPENDS, ie bar_1.0.bb with foo enabled, depends not only on
abc recipe but needs abc also with foo enabled.
