libpayload: only compile drivers/serial.c on machines that it works on

Create a new serial control variable, X86_SERIAL_CONSOLE (I think
    a better name is likely needed) which is only enabled when both
    SERIAL_CONSOLE and ARCH_X86 are defined.

Builds for arm and x86 now. Not tested for Power PC; I think we
    need to decide what to do about that platform (later).
