64-bit PowerPC when linking multiple C++ files referencing the same
method, defined in a common header, when that method had a switch
statement with more than 4 cases. This change fixes compilation of LLVM
tblgen on 64-bit PPC with binutils 2.17.

This prevents warnings like the following during stripping of debug info
from kernel modules on i386:
===> zlib (all)
...
objcopy --only-keep-debug zlib.ko.debug zlib.ko.symbols
objcopy --strip-debug --add-gnu-debuglink=zlib.ko.symbols zlib.ko.debug zlib.ko
BFD: zlib.ko: warning: allocated section `.plt' not in segment
BFD: zlib.ko: warning: allocated section `.got' not in segment
The change made to bfd/elf.c in upstream revision 1.217.4.3 (which was a
revert of an earlier change), caused objcopy on powerpc to fail to copy
debug info from kernel modules. This had to be fixed by applying the
diff from upstream revision 1.243 on top of it.
a variety of bugs in binutils related to handling of 64-bit PPC ELF,
provides a GCC configuration for 64-bit PowerPC on FreeBSD, and
associated build systems tweaks.

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.

Binutils has a "contrib" subdirectory - thus flattening cannot happen
without renaming the upper level contrib directory in a first pass.
Also, don't record this move and remove any keyword expansion.
non-shared object, do not reserve space in .plt and .rela.plt
for regular symbols neither defined nor referenced in shared objects.
This is a backport of rev. 1.101 (sourceware.org repository) to
Binutils 2.15 which fixes the creation of bogus relocations in the
PLT of Firefox and Thunderbird binaries and which in turn caused
them to segfault in rtld(1). This is committed to the vendor branch
as it doesn't represent a local change but the original vendor fix
is from after elf_link_hash_flags was replaced with bitfields.
