autoconf: Override config.guess/.sub in source tree

autoconf has not been released in a number of years. However many
changes have been made to the gnu-config config.guess/.sub since 2.69,
including new architectures, OS variants, etc. In order to enable these
targets without creating patches for the source itself populate the
gnu-config files from the sysroot as is done with autotools recipes.
Whilst it is not possible for the autoconf recipe to bootstrap its
configure task (using the autotools_do_configure), the files can be
manually copied into the target location.
