	(struct bfd_elf_section_data): Change relocs from PTR to
	Elf_Internal_Rela *.
	(struct elf_obj_tdata): Add local_got_offsets field.
	(elf_local_got_offsets): Define accessor macro.

	* elfcode.h (elf_slurp_reloc_table): Don't use the section data
	relocs field.
	(elf_link_record_dynamic_symbol): Make globally visible.  Use
	macro to rename to NAME(bfd_elf,link_record_dynamic_symbol).
	(elf_link_add_object_symbols): If creating a shared library, put
	make all local symbols dynamic.  Don't bother with the
	DYNAMIC_MULTIPLE flags.  Call the check_relocs backend function if
	it is defined.
	(elf_link_create_dynamic_sections): Make globally visible.  Use
	macro to rename to NAME(bfd_elf,link_create_dynamic_sections).  If
	creating a shared library, make sure that _DYNAMIC is added as a
	dynamic symbol.

	(NAME(bfd_elf,record_link_assignment)): If creating a shared
	library, always create symbols, and always make them dynamic.

	Create a copy reloc if ELF_LINK_HASH_NEEDS_COPY is set.

	* configure.in:  Add config for powerpc/Netware.

Ken Raeburn
d3bba67b52 * nm.c (numeric_forward): Treat undefined symbols as "less than" defined
symbols with zero values.  If numeric values are equal, or both symbols are
undefined, sort alphabetically.  Don't assume that the difference of two
bfd_vma values will truncate to "int" and still have the same sign.
(numeric_reverse): Call numeric_forward and negate the result.
(print_symbol_info_bsd): For undefined symbols, print leading spaces equivalent
to the width of a printed bfd_vma, rather than assuming that 8 will look right.

J.T. Conklin
959fea03b5 Changed pattern in gdb_run_cmd to match up to the first newline only.
The old pattern used ".*$", which could, and did, swallow up output
that we were attempting to match elsewhere.
