 You can just warn the user via, e.g. reenabling universal_variant
 (otherwise you will not get it set whatever you do), and:
 {{{
 variant universal {
  ui_msg "Warning, Atlas does not build universal binaries."
 }
 }}}
 and then set the flags according to the machine natural architecture.

 > I would like to also assure, beyond a shadow of a doubt, that the atlas
 package will properly build 64 bit libraries if the ${build_arch} variable
 is set to do so and will build 32 bit if the build_arch is set for that
 and so the 64 bit numpy works as it should against these libraries.

 I didn't challenge that. I build Atlas in 64-bit mode very smoothly.
