Comment (by kencu):

 we're also going to have the fix up the default universal_archs_supported
 in this bit if we want to try to build qt5 universal for arm64/x86_64
 {{{
     proc universal_setup {args} {
         if {[variant_exists universal]} {
             ui_debug "universal variant already exists, so not adding the
 default one"
         } elseif {[exists universal_variant] && ![option
 universal_variant]} {
             ui_debug "universal_variant is false, so not adding the
 default universal variant"
         } elseif {[exists use_xmkmf] && [option use_xmkmf]} {
             ui_debug "using xmkmf, so not adding the default universal
 variant"
         } elseif {![exists os.universal_supported] || ![option
 os.universal_supported]} {
             ui_debug "OS doesn't support universal builds, so not adding
 the default universal variant"
         } elseif {[llength [option supported_archs]] == 1} {
             ui_debug "only one arch supported, so not adding the default
 universal variant"
         } else {
             ui_debug "adding universal variant via PortGroup muniversal"
             uplevel "PortGroup muniversal 1.0"
             uplevel "default universal_archs_supported {\"i386 x86_64\"}"
         }
     }
 }}}
