Once upon a time I made myself an "FSF overlay" for binutils/gcc/gdb/linux
out of then current versions thereof. That overlay had consistent #defines.
Now stock binutils definitions conflict with stock linux definitions, it makes
no sense to build it that way.

That's a question for binutils + xtensa expert, which I'm not (yet).
Sterling? Marc?

I've no idea. That's why I Cc: Bob Wilson, who's contributed FSF overlay
to binutils, maybe he can shed some light on what was intended with
the change.
