PowerPC64 dot-sym testsuite fixes
...
This illustrates quite well why dot-symbols had to go. PowerPC64 gcc
for Linux stopped producing them 12 years ago, but the Linux kernel
still persists in using them so it's necessary to keep and
regression test ld support.

Properly handle indirect symbols

PR ld/3351
* elflink.c (_bfd_elf_update_dynamic_flags): New.
(_bfd_elf_merge_symbol): Update both real and indirect symbol
dynamic flags.
(_bfd_elf_add_default_symbol): Make the real symbol dynamic if
the indirect symbol is defined in a shared library.

symbol has been forced local, don't make the real symbol
dynamic.
(elf_link_check_versioned_symbol): Check indirect symbol.
(elf_link_output_extsym): Use real symbol definition when
reporting indirect symbol error. Check version info for
dynamic versioned symbol.
