x86: Add _bfd_x86_elf_hide_symbol
When there is no dynamic interpreter in PIE, make the undefined weak
symbol dynamic so that PC relative branch to the undefined weak symbol
will land to address 0.
* elf32-i386.c (elf_backend_hide_symbol): New.
* elf64-x86-64.c (elf_backend_hide_symbol): Likewise.
* elfxx-x86.c (_bfd_x86_elf_hide_symbol): Likewise.
* elfxx-x86.h (_bfd_x86_elf_hide_symbol): Likewise.
