x86/insn: Support big endian cross-compiles
x86 instruction decoder code is shared across the kernel source and the
tools. Currently objtool seems to be the only tool from build tools needed
which breaks x86 cross compilation on big endian systems. Make the x86
instruction decoder build host endianness agnostic to support x86 cross
compilation and enable objtool to implement endianness awareness for
big endian architectures support.
