* bfd-in.h (_bfd_elf_fix_excluded_sec_syms): Declare.
	(_bfd_elf_provide_section_bound_symbols): Remove param name.
	Formatting.
	* bfd-in2.h: Regenerate.
	* elflink.c (bfd_elf_gc_sections): Don't call generic function.
	(_bfd_elf_provide_symbol): Formatting.
	(_bfd_elf_provide_section_bound_symbols): Remove all hacks, just
	create section relative syms.
	(fix_syms, _bfd_elf_fix_excluded_sec_syms): New functions.
	* elf32-ppc.c (ppc_elf_set_sdata_syms): Use
	_bfd_elf_provide_section_bound_symbols.
	* reloc.c (bfd_mark_used_section): Delete.
	(bfd_generic_gc_sections): Don't call the above.

	* ldlang.c (strip_excluded_output_sections): Don't call
	bfd_gc_sections.
	* emultempl/elf32.em (gld*_provide_bound_symbols): Move.
	(gld*_provide_init_fini_syms): Move.
	(gld*_before_allocation): Call the above from here..
	(gld*_finish): ..not here.  Call _bfd_elf_fix_excluded_sec_syms.
