You know, it doesn't have to go to the serial port. It can go to
anything. We have at least one platform where it goes to the framebuffer
instead, but getting access to the framebuffer is a whole new load of
platform dependence that we don't want here.
In any case, ifdefing out the callsites is not the correct approach.
We already have this stuff fairly well abstracted, and there's no reason
why this can't be done by defining empty putc() and flush() functions.
