While :remove happens last, it's not recommended to rely on it, especially
when you have nested overrides - there's no guaranteed order of processing
overrides. A better option would be:
GALLIUM_LLVM = " gallium-llvm"
GALLIUM_LLVM:omapl138 = ""
PACKAGECONFIG:append:pn-mesa = "${GALLIUM_LLVM}"
PACKAGECONFIG:append:pn-mesa-pvr = "${GALLIUM_LLVM}"
