   The idea is sound, but the implementation is not very 
   multi-arch-ish.  Is there a runtime way to do this, 
   rather than by using a macro?  The whole purpose of
   multi-arch is that these decisions get made at runtime.
   
It is done at runtime, why do you think I check
GDB_TARGET_IS_SPARC64 in the tm-sp64linux.h case?

For tm-linux.h it can only possibly be one value.

Eventually I want to merge tm-sp64linux.h and tm-linux.h
into one configuration, but I want to merge in all of
my previous work first as that provides the infrastructure I need to
do that properly.
