hypotl(LDBL_MAX, 0.0L) = inf

[airplanemath]

Given that hypot(DBL_MAX, 0.0) = DBL_MAX and hypotf(FLT_MAX, 0.0f) =
FLT_MAX, I suspect this is a problem in hypotl.  Am I missing something?

There is a similar difference in cabsl compared to cabs and cabsf, which
probably has a similar cause.

I attached my test case, which I compile with
gcc -Og -O0 test_cabs_hypot.c -o test_cabs_hypot

What should I expect here?
