4da573d910 Merging of projects/armv6, part 3
r238211:
Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb

This adds a new TARGET_ARCH for building on ARM
processors that support the ARMv6K multiprocessor
extensions.  In particular, these processors have
better support for TLS and mutex operations.

This mostly touches a lot of Makefiles to extend
existing patterns for inferring CPUARCH from ARCH.
It also configures:
 * GCC to default to arm1176jz-s
 * GCC to predefine __FreeBSD_ARCH_armv6__
 * gas to default to ARM_ARCH_V6K
 * uname -p to return 'armv6'
 * make so that MACHINE_ARCH defaults to 'armv6'
It also changes a number of headers to use
the compiler __ARM_ARCH_XXX__ macros to configure
processor-specific support routines.

b375a6d71d Pass --enable-new-dtags to the linker invocation by default. If
desired, one can turn off the generation of post-ELF standard dtags by
overriding it with --disable-new-dtags after the default switch.

Immediate effect of the change is that -rpath path is now stored both
in DT_RPATH and DT_RUNPATH tags, which is the right way to provide
rpath for dynamic linker supporting DT_RUNPATH per specification.

b28518a59a Add experimental support for amdfam10/barcelona from the GCC 4.3 branch.
Initial support for the AMD barcelona chipsets has been available in the
gcc43 branch under GPLv2 but was not included when the Core 2 support
was brought to the system gcc.

AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10
support and made them available. Unfortunately this is still experimental
and while it can improve performance, enabling the CPUTYPE may break some
C++ ports (like clang).

Special care was taken to make sure that the patches predate the GPLv3
switch upstream.

5619a3e4bf Add/improve mips64r2, Octeon, n32 and n64 support in the toolchain.
o) Add TARGET_ABI to the MIPS toolchain build process.  This sets the default
   ABI to one of o32, n32 or n64.  If it is not set, o32 is assumed as that is
   the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE.  This is
   necessary to have a working "cc" if e.g. mips64 is specified, as binutils
   will refuse to link objects using different ISAs in some cases.
o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC.  Add the "octeon"
o) When static linking, wrap default libraries in --start-group and
   --end-group.  This is required for static linking to work on n64 with the
   interdependencies between libraries there.  This is what other OSes that
   support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
   former being what libgcc, etc., check and the latter seemingly being a
   misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
   ISA from the ABI.  Our old defaults were too liberal and assumed that 64-bit
   ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
   the MIPS32 ISA, when we are supporting or will support some systems based on
   earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
   and add flags and code necessary to support Octeon-specific instructions.
   This should also make merging opcodes for other modern architectures easier.
