Yes, if I change function_needs_eh_personality () to return eh_personality_lang instead of eh_personality_any then the test passes. According to PR 20095 the reason for not implementing __gcc_personality_v0 is that the HP unwind library does not implement _UA_END_OF_STACK which is a GCC extension to the standard IA64 unwind ABI and the HP-UX system unwind does not support it so the only way to implement __gcc_personality_v0 is to use the GCC libunwind instead of the HP-UX system one.
