[OE-core] [PATCH] pkgconfig: Ensure pkgconfig RDEPENDS are tracked

[Richard Purdie]

Currently, pkgconfig dependencies get added to -dev packages which install
.pc files however nothing in the system makes bitbake aware of these
dependencies so images can fail with pkgconfig being missing.

This change explictly adds in the pkgconfig RDEPENDS to the -dev packages
and hence makes bitbake aware of the dependency.
