* targets.c, config/i960-bout.mt, hosts/*: added
HOST_BIG_ENDIAN_DEFAULT_VECTOR and
HOST_LITTLE_ENDIAN_DEFAULT_VECTOR because bout archive format
depends on the endianness of the host. Added #define

configuration files in hosts/ (it was already in some).
Various changes to get linker working again for a.out:
* don't set/adjust section file positions or vmas more than once
* use correct page size and segment size when calculating them
* deal with some variations in a.out implementations
Tested on sun4 and sun4->sun3 so far, will be testing further but
needed to get wider exposure&testing. See ChangeLog for details.

* coffcode.h (coff_write_relocs): Write out swapped reloc, not
pre-swapped version.

coffcode.h
* coffcode.h: Started to change the way machine dependencies are
handled, from the nest of #ifdefs to macros defined in the
including coff-<foo>.c
* opncls.c (bfd_close_all_done). Added so that generative
programs like gas can close a bfd without causing bfd confusion.
* libbfd.h (changed becuase of protos)
* amdcoff.c: messed with the way that jmp displacements are
calcualated. This may not yet be totally correct.
* archive.c (coff_write_armap): rewrote the way that ranlibs are
written out.
* coffcode.h (fixup_symbol_value): now doesn't core dump if a non
abs symbol has no section (like a register symbol).
(coff_write_symbol) now zeros auxent before filling it up to help
with sensitive applications.
* libbfd.c (bfd_write_bigendian_4byte_int): added.
* bfd.c: Added macros to enable gas to swap coff records.
* coffcode.h: Make the coff_swap_*_out routines return the number
of bytes swapped, and cleaned up their prototypes.
