VAX ELF toolchain, using `%' as the register prefix. Heavily based upon
NetBSD.

ELF toolchain for m68k, following the SysV/m68k ABI (32-bit types aligned on
32-bit boundaries, function return values being in %a0 instead of %d0 if they
are declared as pointers, and in fp registers if they are floating point types).

Compiler configuration bits (including a few m68k PIC code generation fixes)
borrowed from NetBSD.

m88k ELF toolchain, supporting static binaries only so far.

Assembler supports a register prefix of `#' when configured for SVR4, and `%'
when configured for OpenBSD. Pseudo-ops do not need a leading dot, except
when configured for OpenBSD, allowing the `set' instruction to be recognized
correctly.

Based upon various unfinished or unreliable works, including smurph@'s early
work in 2003, my own attempts in 2004 and 2005, and Michael Kato's binutils
2.15 diff from 2005. Support for register prefixes, as well as fixing an
evil off-by-one in resolving 16-bit pc-relative relocations in ld (which would
only affect kernel .S files branching to global symbols), came as part of the
2012 work.

Not enabled yet (needs Makefile.bsd-wrapper, bfd/config.bfd and
gdb/configure.tgt updates to completely enable) so as not to disturb the
existing a.out toolchain builds; will hopefully be enabled very soon.

Define superH obsd-specific emulations for ld, and use it by default.

Provide openbsd emulation for mips64el as we do for mips64.

Merge conflicts, bringing our changes back in:
- extra $(SHELL) and sugar for make (so that files not mode +x still work)
- safer temp file handling
- our W^X binary layout changes in ld
- OpenBSD policy for library file selection in ld
- arm and m88k changes which were not merged in time for official 2.15
- bfd core file handling
- a couple typos

New for 2.15:
- ld(1) and as(1) manpages now generated at build time
- binutils/stabs.c reverted to use our in-tree libiberty for now
- we still use our VIA C3 crypto code over stock binutils, as it recognizes
more instructions
- new emulations for OpenBSD on mips64 machines, to help OpenBSD/sgi
- relaxed %f# handling in gas on OpenBSD/sparc64 (same as was in 2.14)

Tested on all platforms by various people; special thanks to sturm@ and
otto@.

Resolve merge conflicts, adjust method of W^X handing (.sh files)
remove testsuites (not useable) remove mmalloc (not part of new binutils).

use common elf.sc instead of own hppaobsd.sc, catch up w/ dale's elf work for hppa; drahn@ lots of helps and ok

provide our own path for generating the ldscripts and tweak it accordingly; fgsch@ ok

- Sync changes between source and generated files (ie., changes existing
only in the generated files).
- Regen.

Whenever is possible, changes should be done to the source files (.am, .in).
That way is easier to track and merge local changes when importing.

hppa pieces; don't regenerate yet.
