Unfortunately CPU_LITTLE_ENDIAN is only available on architectures
that support two endiannesses. So the above will preclude e.g. x86, which is
where most ISDN users are.

One solution is to move CPU_LITTLE_ENDIAN and CPU_BIG_ENDIAN to the
common Kconfig parts. After that, the dependency above can just become

    depends on CPU_LITTLE_ENDIAN && PCI.

when I'm talking to journalists I just say "programmer" or something like that.
