Yes, that seems about right - can be combined with either tests on target
names for __float128, or with the compile test for _Float128 (provided
that dg-add-options float128 - which is preferred to hardcoding the
particular options in the individual tests - can be made to take effect
before the compile test for _Float128 gets run).
