  1. Don't set $host_alias as that confuses autoconf 2.70 

    Autoconf 2.70 is more careful about cross compilation, so with this
version using AC_FUNC_MMAP implies AC_CANONICAL_HOST and hence computes
$build/build_alias/host/host_alias/etc. Setting $host_alias ourselves
interferes with that. Hat tip Matthias Klose (via debbug#978835).

As autoconf 2.70 implicitly uses AC_CANONICAL_HOST, it requires (and its
autoreconf --install installs) config.guess and config.sub. Ignore those,
and ignore install-sh as well for good measure.
