May I suggest the following instead:

relocatable_native_pcfiles () {
	files=$(find ${SYSROOT_DESTDIR}${libdir}/pkgconfig -name '*.pc' 2>/dev/null)
	if [ "$files" ]; then
		rel=${@os.path.relpath(d.getVar('base_prefix'), d.getVar('libdir') + "/pkgconfig")}
		sed -i -e "s:${base_prefix}:\${pcfiledir}/$rel:g" $files
	fi
	files=$(find ${SYSROOT_DESTDIR}${datadir}/pkgconfig -name '*.pc' 2>/dev/null)
	if [ "$files" ]; then
		rel=${@os.path.relpath(d.getVar('base_prefix'), d.getVar('datadir') + "/pkgconfig")}
		sed -i -e "s:${base_prefix}:\${pcfiledir}/$rel:g" $files
	fi
}
