fix 32bit intel detection for 32bit mxe target 

mxe leaves CMAKE_SYSTEM_PROCESSOR empty, so detect if mxe is being used
and set the variable based on CMAKE_TOOLCHAIN_FILE, this allows the
32bit asm to compile under mxe.

Also if no toolchain file is being used and CMAKE_SYSTEM_PROCESSOR is
empty, fall back to CMAKE_HOST_SYSTEM_PROCESSOR.
