* coff-m68k.c (m68k_howto2type, SELECT_RELOC): new function to
work out a coff relocation type from a howto's attributes rather
than using the input r_type field. This fixes PR1677 and allows

relative to an absolute symbol, use the right symbol index.
* reloc.c (bfd_perform_relocation): do a partial link for coff
relocs right.
Lints for bfd_reloc_code_type->bfd_reloc_code_real_type, and
correct calling of howto special functions and fixes from Raeburn
for gas<>bfdness
* archures.c: nuke bfd_reloc_code_type
* bout.c, cpu-h8300.c, coff-i960.c, coff-m88k.c: special function lint
* coffcode.h (styp_to_sec_flags): STYP_INFO is marked as
SEC_NEVER_LOAD, various other bfdgas newness
* reloc.c->libbfd.h: change protype of bfd_default_reloc_type_lookup
* targets.c: change jump table vector to above
* working reloc lookup support
* better support for creation of COFF files from scratch
* misc doc changes, macro tweaks, "const" additions, typo fixes, etc.
* one or two ugly kludges that should get cleaned up (but what's one
or two more, in BFD?)
See ChangeLog for details.
bout.c (b_out_squirt_out_relocs): treat abs sumbols the right way.
* reloc.c (bfd_perform-relocation): don't relocate refs to
absolute symbols if doing a partial link.
