We need some way to pass -mbig-endian to the linker during the LTO link stage, otherwise we get a waning like
arm-linux-gnueabi/bin/ld: arch/arm/lib/clearbit.o: compiled for a big endian system and target is little endian for each file we link in. There is probably a better method of passing that flag, I'm just adding it to a different hack that I added earlier for x86 LTO here.
