Ah, there it is! I was looking somewhere else.

Yeah, but ac_tool_prefix is set if --host is given, which affects
the compiler chosen, etc. This is actually the source of Akim's
comment: Ian Taylor was wondering why this behaviour had changed
So it is good to clear up with Akim & the autoconf developers

Yes, I understand. That's quite clever, actually, and I think you are
on to a good thing. You have convinced me that setting --build is the
right thing to do.
I just want to be sure that we understand fully the ramifications
of setting --host.
