I think we have one architecture in the kernel that determines endianess from
the way that the toolchain is built. What all the others do it to have a Kconfig
option, at least CONFIG_CPU_BIG_ENDIAN that is used to pass -mbig-endian
or -mlittle-endian to the compiler. You should do it that way so you can use
any toolchain with any kernel configuration.
