[U-Boot] [PATCH v4 13/21] distro: Move to compiler based target architecture determination

[Alexander Graf]

Thanks to CONFIG_SANDBOX, we can not rely on config options to tell us
what CPU architecture we're running on.

The compiler however does know that, so let's just move the ifdefs over
to compiler based defines rather than kconfig based options.
