Fix typo: s/LIBSERACHPATH/LIBSEARCHPATH/g

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).

Updated Bmake framework for Binutils 2.15.

Properly quote the lib path.

Stage 3 of dynamic root support, con't.
'ld' should also search /lib for dynamic libraries.

Change the default emulation to elf64_sparc_fbsd. This emulation knows the
correct spelling of our rtld.

Make it easier to change the native emulation.

Tested on: alpha, i386, sparc64

Uggg!! LD ME HARDER!!
Rev 1.2 changed the default emulation from ``elf64_sparc'' to ``elf32_sparc''
and I never noticed it after my review of rev 1.1. Backing the change of
the default emulation out, and Wa-la!, I can now build a native [and usable]
binutils. WTF, the "-m elf64_sparc" parameter handed to `ld' by `gcc'
wasn't DTRT is beyond me.

Support linking with -z combreloc (combine and sort reloc sections) and with
--shared -z combreloc (shared library, combine & sort relocs)

Set the SCRIPTDIR to be rooted at TOOLS_PREFIX rather than DESTDIR.
(the two may be different (ie, build vs. runtime))
Allow ldscript's SEARCH_DIR do be rooted somewhere other than `/'.
(in this case at TOOLS_PREFIX)

These changes are most helpful during `make buildworld' so that the shared
libs built in the middle of `make buildworld' are used vs. the ones in
/usr/lib on the build machine.

You know the last revision will work better if the TARGET_TUPLE is set
conditionally....

Allow easier override of the configure tuple, in case you wanted to build
as "powerpc-obrien-freebsd" rahter than "powerpc-unknown-freebsd" for example.

Clean up the formatting.

`stringify.sed' has been replaced by `astring.sed' [on ANSI-C systems].

MFC: Upgrade to Binutils 2.10.0.

Build and install the elf32_sparc ld(1) scripts and make elf32_sparc
the default emulation.

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