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

[Clemens Eisserer]

Hi Burton,

Indeed, the luajit package contained the luajit.pc file as expected.

The issue was the _$PN appended to DEPENDS, when I removed it the build
succeeded:
changing DEPENDS_${PN} = "luajit" to DEPENDS = "luajit" did the trick.

However, I am still puzzled what happens here and why it worked before.

Br, Clemens
