* elf32-m32c.c (m32c_elf_check_relocs): Use bfd_make_section

Browse Source 
"anyway" variant when creating .plt.
	(m32c_elf_relax_plt_section): Remove redundant test and unused param.
	(m32c_elf_relax_section): Test SEC_LINKER_CREATED before calling
	m32c_elf_relax_plt_section.
	* elfxx-mips.c (mips_elf_create_got_section): Use make anyway variant
	when creating .got and .got.plt.
	(_bfd_mips_elf_final_link): Likewise for .rtproc, and use
	bfd_get_linker_section.
	* sunos.c: Similarly throughout.
