The three bugs below point test failures in a couple of the printf
tests due to them exercising C99 features not present in the default
runtime on the targets (the h and hh length modifiers on HP-UX 11.11
and the a format specifier in Newlib).  As suggested in PR 78959,
the attached patch committed in r244298 adds
the { dg-require-effective-target c99_runtime } directive to make
the tests conditional on support for those features.
