The series needs:

 TUNE_CCARGS_x86 := "${@oe_filter_out('-mfpmath=sse', '${TUNE_CCARGS}', d)}"
+TUNE_CCARGS_x86-64 := "${@oe_filter_out('-mfpmath=sse', '${TUNE_CCARGS}', d)}"

since the x86 override doesn't cover x86_64. I'll queue that and run yet
another build. We do have another poky-tiny issue too:
