Thanks, I pushed the following slightly-different
(and I hope clearer) patch.  I don't understand
the disagreement about what --host and --build
should do (I try not to do cross-builds myself...)
but at least this helps document what autoconf
currently does, and it can be changed if the behavior
needs to be changed.

Subject: [PATCH] doc: document --build and cross-compilation better

* doc/autoconf.texi (Specifying Target Triplets): Mention that

cross-compilation.  Problem reported by Bruno Haible in:
