- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things. Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.

MAJOR cleanup of the Bmake framework.
This includes removing all vestiges of the old not-really supported
ability to build cross tools targeting non-FreeBSD systems, such as
m68k Lynx and NetBSD. Move as much duplicated code from platform
Makefiles into the shared Makefiles. Add a simple mechanism for
specifying ELF 'ldscripts'. Also share as many .h files as possible
(now a single bfd.h vs. one per platform).

With tmm's latest change to the sparc64 dynamic loader, we can remove this
hack to binutils and use the stock sparc64 sources.

Move the elf32-target.h and elf64-target.h targets from the MD
makefiles to the centralized makefile. This not only reduces
duplication, it also makes the MD quirks stand out better and
thus improves maintenance.

Commit a crude hack so we get sparc64 snapshots working again with a
stable ld.so. We need to revisit the rtld-elf/sparc64/rtld_start.S
rev. 1.5 and rtld-elf/sparc64/rtld_machdep.h rev. 1.5, which was
suppose to allow stock Binutils 2.13 (and later) to be used.

Cleaner support of a DEFAULT_VECTOR.

Handle the "HAVE_" defines via the VECS list.

Clean up the formatting.

MFC: Upgrade to Binutils 2.10.0.

Add sparcnetbsd support and cleanup style so that this looks nearly
identical to Makefile.sparc.

Add support for the sunos_big_vec format as well.

First cut at the (non-contrib) bits needed to build the binutils
distribution for FreeBSD/Sparc64.
