    Set EI_OSABI to ELFOSABI_GNU for local IFUNC symbols

    Since the backend elf_add_symbol_hook isn't called on local symbols,
    the EI_OSABI field isn't to ELFOSABI_GNU where are local IFUNC symbols.
    This patch changes the x86 backends to set has_gnu_symbols if there are
    relocations against IFUNC symbols.  Other backends with IFUNC support
    may need a similar change.

    This patch also changes the type of has_gnu_symbols from bfd_boolean to
    enum elf_gnu_symbols.
