Jim Kingdon
3f99570ec9 * aout-target.h, netbsd386.c: Replace NO_SWAP_MAGIC with SWAP_MAGIC,
and do the swapping here rather than calling ntohl from the N_*
	macros.  This cleans up assumptions about the size of a host long,
	the existence to ntohl, etc.

gives the external symbol number in the elf object file, since
local symbols must come before global symbols.
(elf_sym_extra): New macro.
(elf_symtab_map): Delete, in favor of using Elf_Sym_Extra.
* elfcode.h (elf_map_symbols): Use Elf_Sym_Extra to map internal

section symbols for sections that have SEC_ALLOC set, and have non-zero size.
(elf_symbol_from_bfd_symbol): If udata is NULL, and this is a section symbol,
look up the section in the list of section symbols, and set the udata pointer
appropriately.  Otherwise, if udata is still NULL, fail an assertion, and use
0, instead of dropping core.
