I agree, and suppose the project should decide it on the demands, for
which archs they should allocate space in Debian's master repository.
But it's good if we would have tools capable of managing all possible
architectures.

Sorry I could not provide enough explaination. (Niibe?)
It's very difficult for the runtime to handle this kind of ABI
incompatibility; and it's not recommendable to redefine the ABI
because it was defined by Hitachi and has been used by many other
compilers and tools (not GNU) for a long time.
