    layerscape: fix PKG_BUILD_DIR for packages
    
    PKG_BUILD_DIR was defined with quoting PKG_VERSION in
    layerscape package makefiles. Now PKG_VERSION has been
    removed from these makefiles. When PKG_BUILD_DIR quotes
    PKG_VERSION, '=' should be used instead ':=' to make
    sure PKG_VERSION has been defined in common makefile.
