* ld-elfvsb/main.c: Ensure visibility_def and visibility_func are

  actually referenced (gcc 3.4 eliminates comparisons of addresses
  of global symbols with NULL).
* ld-selective/selective.exp: Suppress -fvtable-gc tests for gcc
  3.4.0 and above, as this option and its functionality is no longer
  supported, making these tests fail).
