Bug 748001 got rid of some implicit rules that media/libvpx/Makefile.in was relying on to make the obj_int_extract approach to extracting C struct offsets for the libvpx asm work. We didn't notice because
a) the decoder only needs these offsets on ARM, and ARM always uses gcc, which does this a much better way (without obj_int_extract), and
b) the encoder is not built by default.
