Use bfd_link_align_section in a few more places

Some of these aren't relevant to the relro bug.  Some are.  They all
matter if early estimation of section layout needs to be good.

	PR ld/32690
	* elf32-bfin.c (bfin_adjust_dynamic_symbol),
	* elf32-hppa.c (elf32_hppa_late_size_sections),
	* elf32-microblaze.c (microblaze_elf_adjust_dynamic_symbol),
	* elf32-nds32.c (nds32_elf_adjust_dynamic_symbol),
	* elf64-ppc.c (size_global_entry_stubs),
	* elflink.c (_bfd_elf_tls_setup),
	* elfxx-mips.c (mips_elf_add_la25_intro),
	(mips_elf_add_la25_trampoline),
	(_bfd_mips_elf_adjust_dynamic_symbol),
	* elfxx-x86.c (_bfd_x86_elf_late_size_sections): Use
	bfd_link_align_section to ensure correct output section
	alignment.
