I'm not really trying to build a gdbserver that can handle multiple
architectures/targets, but rather fix the netbsd/ppc gdbserver that
got broken when the gdb ppc target was multi-arched.  In this case,
REGISTER_BYTES and MAX_REGISTER_RAW_SIZE which used to be defined as
constants, are now gdbarch functions.  This causes compile time 
failures since these macros are used to size arrays.

I'm looking for direction for fixing this.
