I think only xtensa, all others already define CONFIG_CPU_BIG_ENDIAN
conditionally, and include the right header depending on that.
For xtensa, the decision is apparently made by the toolchain, and the
kernel just detects the macros set by the compiler, but that is slightly
fragile because it prevents us from making Kconfig decisions based on
endianess.
