headline: XFAIL format tests on hppa*-*-hpux* due to snprintf precision
tldr: Two gfortran tests are XFAILed on hppa*-*-hpux* because snprintf provides insufficient precision for long doubles.

The gfortran test cases default_format_2.f90 and default_format_denormal_2.f90 are now marked as expected to fail (XFAIL) on the hppa*-*-hpux* platform. This is due to a limitation in the snprintf function on this platform, which only provides 33 digits of decimal precision for long double values. This precision is insufficient to uniquely represent long double values, causing the tests to fail.
