Comment (by kencu):

 most meson ports have a block  something like this in them to fix this:
 {{{
 if {![info exists universal_possible]} {
     set universal_possible [expr {${os.universal_supported} && [llength
 ${configure.universal_archs}] >= 2}]
 }
 if {${universal_possible} && [variant_isset universal]} {
     foreach my_arch {ppc ppc64 i386 x86_64 arm64} {
         # strip the automatic setting of host, meson does not accept
         set merger_host(${my_arch}) ""
     }
 }
 }}}

 the automatic adding of the {{{host}}} information by the {{{muniversal}}}
 portgroup is not accepted by meson.
