Please confirm that it no longer fails.

There is now a dg-effective-target check which does not run the test case if
for the highest available floating-point data type (here: REAL(16)) no sqrt
function is available.

Thus, the test case will no longer fail as it is not run.

I think one could add - for HPUX - a configure test whether (a) libquadmath can
be build, (b) whether "long double" and __float128 are the same, and (c)
whether "sqrtl" is not available. If this is fulfilled, one could provide the
symbols in libquadmath. But that's a different issue and should be started by
someone who has access to such a system.
