H.J. Lu ca3fe95e46 Add extern_protected_data and set it for x86 
With copy relocation, address of protected data defined in the shared
library may be external.  This patch adds extern_protected_data and
changes _bfd_elf_symbol_refs_local_p to return false for protected data
if extern_protected_data is true.
