This patch provides basic support for powerpc64le as an LLVM target.
However, use of this target will not actually generate little-endian
code. Instead, use of the target will cause the correct little-endian
built-in defines to be generated, so that code that tests for
__LITTLE_ENDIAN__, for example, will be correctly parsed for
syntax-only testing. Code generation will otherwise be the same as
powerpc64 (big-endian), for now.
The patch leaves open the possibility of creating a little-endian
PowerPC64 back end, but there is no immediate intent to create such a
thing.
The LLVM portions of this patch simply add ppc64le coverage everywhere
that ppc64 coverage currently exists. There is nothing of any import
worth testing until such time as little-endian code generation is
implemented. In the corresponding Clang patch, there is a new test
case variant to ensure that correct built-in defines for little-endian
code are generated.

to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of
gcc, where it will silently accept an unknown -Wno-foo option, but will
generate an error for a compile which uses -Wno-foo if that compile also
triggers any warnings.

gets placed inside a main function, and should not itself be a main
function. This is silently hidden in GCC-hosted builds because the
inner main looks like a nested function declaration, which GCC supports.
In builds with compilers which do not support nested functions (by default),
this was causing an error, which caused these autoconf checks to fail,
leaving their options disabled.
This fixes test/Feature/load_module.ll on x86_64-unknown-linux-gnu
llvm-gcc selfhost builds, among other things.
This also includes a regenerated configure, as the diff is small and telling.

use of that option with it. This eliminates an imprecise "Linux"
test, and should help support old versions of gold.

HAVE_{BI,STD,FWD}_ITERATOR and HAVE_NAMESPACES were not used in the code.
bison and flex are no longer used.
CAN_DLOPEN_SELF was never used either.
AC_PROG_LIBTOOL is not needed since we don't use libtool, we only need the
libltdl checks for dlopen.
Add check for AR, it used to be done by AC_PROG_LIBTOOL.
AC_TYPE_SIGNAL is deprecated, follow autoupdate's suggestion and replace with
void.
Remove unused m4 files.
Configure can now be generated using autoconf 2.65 too, without any warnings!

with a 64-bit kernel, which confuses LLVM. Make LLVM double-check this by
checking which defines the system gcc actually sets.

that all the Makefiles changed mode.
Fix this by tellint install-sh to chmod
only to 0644, these are not executable files after all!

plain wrong since $module was never defined so we always get .so which is
broken on Darwin. Just force it to .dylib.

Demote check for bison from error to warning and make sure that the
makefile can handle an empty definition for BISON variable.

Fix problem setting the USE_{program} variable. It should be set to a
Makefile variable definition line, not just "1". Problem noted by
Kenneth Hoste.

Fix problem noticed by Kenneth Hoste. The wrong name for a variable was
being set and subsequently uses of the correct name were empty.

Update ltld.[ch] to version 1.5.22.
Correct the notes about updating these tools (autoconf/README.TXT)
Add configure options for getting the correct option for including a whole
archive when linking.
