[PATCH]: Restore bootstrap with gcc < 4.3

[Uros Bizjak]

Hello!

The new test finalization self tests fail wigh gcc < 4.3 due to the
way need_finalization_p is defined:

template<typename T>
static inline bool
need_finalization_p ()
{
#if GCC_VERSION >= 4003
  return !__has_trivial_destructor (T);
#else
  return true;
#endif
}

It is obvious that checking for

   ASSERT_FALSE (need_finalization_p <test_struct> ());

will always fail. Checking need_finalization_p is meaningless with gcc < 4.3.

2016-06-13  Uros Bizjak  <ubiz...@gmail.com>

    * ggc-tests.c (test_finalization): Only test need_finalization_p
    for GCC_VERSION >= 4003.

Bootstrapped on x86_64-linux-gnu, CentOS 5.11.

OK for mainline?

Uros.
