[yocto] pkg-config does not find "luajit" since upgrade to sumo

[Burton, Ross]

All I can say is stop digging around random paths and actually ask the
system the questions you need answers to.

- Does my recipe depend on luajit.
Check that you have DEPENDS=luajit.

- What files does luajit ship.
$ oe-pkgdata-util list-pkg-files -p luajit
Does that include a /usr/lib/pkgconfig/luajit.pc?
