SRC_URI_append_gfex-prototype3: gfex-prototype3 is appended to SRC_URI expansion. See log.do_fetch on how it looks for the required files

system.dts is a dummy dts file, I think it is better to have it removed, we usually remove during do_configure step. You should compile just the system-top.dts, this includes all the other dtsi files
