commit 110a58b9f91c66f743c01a2c217243d94c899c23 upstream.
uImage boot wrapper should not use SPE instructions, like kernel itself. Boot wrapper has already disabled Altivec and VSX instructions but not SPE. Options -mno-spe and -mspe=no already set when compilation of kernel, but not when compiling uImage wrapper yet. Fix it.
