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).
* ld-elfvsb/elfvsb.exp: xfail non-pic shared library tests for
non 64-bit hppa*-*-linux* targets.
* ld-elfvsb/main.c (main_visibility_check): Cast value returned by
visibility_funptr () to a function pointer.
* ld-shared/shared.exp: xfail shared (non PIC), shared (non PIC, load
offset), and shared (PIC main, non PIC so) tests for non 64-bit
hppa*-*-linux* targets.

* elf-bfd.h (ELF_LINK_DYNAMIC_DEF): New.
(ELF_LINK_DYNAMIC_WEAK): New.
* elflink.h (elf_merge_symbol): Add one argument to indicate if
a symbol should be skipped. Ignore definitions in dynamic
objects for symbols with non-default visibility.
(elf_add_default_symbol): Adjusted.
(elf_link_add_object_symbols): Check if a symbol should be
skipped. Don't merge the visibility field with the one from
a dynamic object.
(elf_link_check_versioned_symbol): Use undef_bfd.
(elf_link_output_extsym): Warn if a forced local symbol is
referenced from dynamic objects. Make non-weak undefined symbol
with non-default visibility a fatal error.
