[COMMITED]: rx.h: Define supported debugging types.

[Nick Clifton via Gcc-patches]

Hi Guys,

  I am applying the patch below to fix a problem building the rx port.
  The rx.h header file defines PREFERRED_DEBUGGING_TYPE but it was not
  defining the types of debugging it preferred.  This results in the
  definition in defaults.h being triggered and the compiler complaining
  about a redefinition.

Cheers
  Nick
