Move elf64_alpha_local_undefweak_p to elf-bfd.h (elf_link_local_undefweak_p)

Since local weak undefined symbol value is always 0, handle TLS
relocations against local weak undefined symbols separately.

* elf-bfd.h (elf_link_local_undefweak_p): New function.
* elf64-alpha.c (elf64_alpha_relocate_section): Handle TLS
relocations against local weak undefined symbol value separately.
