* 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.
(elf_link_add_object_symbols): Likewise. If the indirect
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.

that only PT_LOAD headers include file header and section headers.

assert PT_GNU_RELRO header does not include file and section headers.
Compare first section vma rather than PT_LOAD p_vaddr against
relro_start when looking for PT_LOAD covering PT_GNU_RELRO. Replace
abort with assertion.
"anyway" variant when creating .plt.

m32c_elf_relax_plt_section.

that forces st_target_internal to equal 1, since tc_frob_symbol
seems to need adjusting.

* elf.c (_bfd_elf_map_sections_to_segments): Disregard bss type
sections at end of PT_LOAD segment when searching for segment
that contains end of relro extent.
