I don't understand why arm-poky-linux-gnueabi-ar says "invalid option -- 'g'" whereas this option doesn't appear in arm-poky-linux-gnueabi-ar args list in the command line (see log) ?
It seems like ar doesn't take -lgio-2.0 arguments. I think you're supposed to put the path to the libgio-2.0.so file directly on the command line, not via a -l argument.
(In the ar manpage it says the -l argument is accepted but ignored, so I suspect G.M. is correct in the comment in saying that -lgio-2.0 is where the -g comes from)
