* elf32-mips.c (mips_elf_link_hash_entry): Add a new field,
	readonly_reloc, to record if a relocation in the .rel.dyn
	section is against a read-only section.
	(mips_elf_link_hash_newfunc): Initialize the readonly_reloc
	field to false.
	(_bfd_mips_elf_check_relocs): Record if there is a relocation
	in the .rel.dyn section against a read-only section by setting
	DF_TEXTREL or readonly_reloc.
	(_bfd_mips_elf_copy_indirect_symbol): Copy readonly_reloc if
	it is true.
	(_bfd_mips_elf_adjust_dynamic_symbol): Record DF_TEXTREL if
	there is a relocation in the .rel.dyn section against a
	read-only section.
	(_bfd_mips_elf_size_dynamic_sections): Set DT_TEXTREL if
	DF_TEXTREL is set.
