It's there in autoconf:

AC_ARG_ENABLE([experimental-targets],AS_HELP_STRING([--enable-experimental-targets],
    [Build experimental host targets: disable or target1,target2,...
     (default=disable)]),,
    enableval=disable)

if test ${enableval} != "disable"
then
  TARGETS_TO_BUILD="$enableval $TARGETS_TO_BUILD"
fi

AC_SUBST(TARGETS_TO_BUILD,$TARGETS_TO_BUILD)
