I am adding a package that has dependencies on QT pkg-config pc files.  I
see the pkg-config pc files in
output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/share/pkgconfig/, but
I don't see any pkg-config files installed to target.  the QQmlApplication
code is trying to include multiple qt packages but they are not found.
Running "pkg-config --list-all" results in none found at all.

How do I get pkg-config pc files installed to the target?
