Properly handle dynamic reloc against normal symbol
We shouldn't issue an error for read-only segment with dynamic IFUNC
relocations when dynamic relocations are against normal symbols.

PR ld/19939
* elf-bfd.h (_bfd_elf_allocate_ifunc_dyn_relocs): Add a pointer
to bfd_boolean.
* elf-ifunc.c (_bfd_elf_allocate_ifunc_dyn_relocs): Updated.
Set *readonly_dynrelocs_against_ifunc_p to TRUE if dynamic reloc
applies to read-only section.
* elf32-i386.c (elf_i386_link_hash_table): Add
readonly_dynrelocs_against_ifunc.
(elf_i386_allocate_dynrelocs): Updated.
(elf_i386_size_dynamic_sections): Issue an error for read-only
segment with dynamic IFUNC relocations only if
readonly_dynrelocs_against_ifunc is TRUE.
* elf64-x86-64.c (elf_x86_64_link_hash_table): Add
readonly_dynrelocs_against_ifunc.
(elf_x86_64_allocate_dynrelocs): Updated.
(elf_x86_64_size_dynamic_sections): Issue an error for read-only
segment with dynamic IFUNC relocations only if
readonly_dynrelocs_against_ifunc is TRUE.
* elfnn-aarch64.c (elfNN_aarch64_allocate_ifunc_dynrelocs):
Updated.
