Thanks.

I still feel that this documentation can be improved:

  - It currently says that --host "enables cross-compilation", which is
    half right and half wrong (it's right regarding host-type-TOOL programs,
    and it's wrong regarding AC_RUN_IFELSE).

  - It says "For historical reasons, whenever you specify ‘--host’, be sure to
    specify ‘--build’ too". This sentence is obsolete. I'm building packages
    with --host and without --build for 15+ years, and it works fine.

  - To care about the case of the buggy Wine emulator and how to avoid it,
    a sentence could be useful.

Here's a proposed doc patch.
