Comment (by thomie):

 This may be obvious, but that default is decided in `configure.ac`:
 {{{
  dnl ** Do an unregisterised build?
  dnl --------------------------------------------------------------
  case "$HostArch" in
      i386|x86_64|powerpc|arm)
          UnregisterisedDefault=NO
          ;;
      *)
          UnregisterisedDefault=YES
          ;;
  esac
 }}}

 Last changed in commit f917eeb824cfb7143dde9b12e501d4ddb0049b65. But
 before adding `|sparc` to that list, at least #8847 needs to be fixed
 first.
