This doesn't work in supposedly CPU-independent source code files.

Let's take percpu.h as an example. We need to include it in
<rtems/score/thread.h> -- the main header for thread scheduling that
is included by virtually every source file in the supercore. We can't
include the CPU-dependent headers here, unless we use the CPP #if-elif
cascase as mentioned by Sebastian.
