[PATCH] rs6000.c ELF bits inclusion

[David Edelsohn]

	Isn't this a question of whether config/svr4.h assumes to much?

	Why is the right solution to change rs6000.c?  Maybe it is or
maybe it isn't.  To me this is a broader design question than FreeBSD
relying directly upon elfos.h and sweeping the changes under the rug.

	config/freebsd.h is duplicating pieces of config/svr4.h.  This
causes a maintenance problem.  Is there no way to separate the
system-specific pieces of config/svr4.h from the ABI-specific pieces so
that FreeBSD could shared the latter with other SVR4-based system?
