c72f2fb2bb Make bfd.link_next field a union

file.

cb22ccf411 This patch causes local GOT entries addressed via a 16-bit index to
be placed towards the front of local GOT space, while entries addressed
via a 32-bit index are placed towards the rear.

Provided that there are fewer than ~16K local GOT entries addressed via
a 16-bit index in total, this should eliminate any relocation overflows
caused by such GOT entries being allocated beyond the addressable range.

	field.  Add assigned_low_gotno and assigned_high_gotno fields.

	(mips_elf_set_global_gotidx): Replace uses of assigned_gotno
	with assigned_low_gotno.
	(mips_elf_multi_got): Initialize assigned_low_gotno and
	assigned_high_gotno in secondary GOTs.  Use assigned_low_gotno
	in place of assigned_gotno when handling global GOT entries.
	(mips_elf_lay_out_got): Initialize assigned_low_gotno and
	assigned_high_gotno.
	(_bfd_mips_elf_finish_dynamic_sections): Account for a possible

5db3e65d39 The PT_DYNAMIC segment was being hard coded to have read, write, and
execute permission regardless of the underlying PT_LOAD segment permissions.
Deleting this code allows the default linker behavior which is to set the
dynamic segment to the same permissions as the sections that make it up.

This change alters one existing test case to check the segment flags for
PT_DYNAMIC.
