The Apple buildbots are set up to pass --target to configure for both
cross- and non-cross-compile builds, and the standard autoconf response
to this is to set the program prefix to '<target>-'. Until we can figure
out the proper way to handle this (don't pass --target? pass an explicit
--program-prefix=""? don't auto-populate program_prefix with target_alias?)
it's more important to keep the buildbots running.

This reverts r164633 / ba48ceb1a3802e20e781ef04ea2573ffae2ac414.

to store additional flag options since too many things can
and do override CPPFLAGS. Also, this is exported, unlike CPPFLAGS
so it can be actually used elsewhere. This should enable us
to remove the AC_SUBSTs in the intel checks, but I have no way
of testing it.

Add a comment that the 'check-lit' rule is really just a legacy of
having two test runners.

optional library support to the llvm-build tool:
 - Add new command line parameter to llvm-build: “--enable-optional-libraries”
 - Add handing of new llvm-build library type “OptionalLibrary”
 - Update Cmake and automake build systems to pass correct flags to llvm-build
   based on configuration

llvm-ld is no longer useful and causes confusion and so it is being removed.

* Does not work very well on Windows because it must call a gcc like driver to
  assemble and link.
* Has lots of hard coded paths which are wrong on many systems.
* Does not understand most of ld's options.
* Can be partially replaced by llvm-link | opt | {llc | as, llc -filetype=obj} |
  ld, or fully replaced by Clang.

I know of no production use of llvm-ld, and hacking use should be
replaced by Clang's driver.

 - On OS X 10.7+ this is apparently recommended practice. This maybe should
   become a configurey thing one day, but I'm not sure it is right to
   automatically turn it on.

sure we don't use it with compilers that don't support it.

Clang builds. The detection logic for compilers that support the warning
isn't working. Rafael is going to investigate it, but didn't want people
to have to wade through build spam until then.

On Cygwin/MingW, add SharedLibDir and LLVMToolDir to the library search path, since shared libraries are placed in 'bin'. (static libraries are still in 'lib').

This was disabled years ago because of a bug in GCC 4.1, which is
on our "broken compilers" list for other reasons. Saving ~500k
on a clang binary (Release+Asserts) is well worth dropping support
for it.

We currently disable it for shared libraries (where it would bring
the biggest win) because clang is broken (PR11642).

IMPORTANT: If you're doing incremental builds you may get tons of
linker warnings. make clean will fix them.

   - Another reapply of r144300, with hopefully one last fix.

Original commit message:
llvm-config: Replace with C++ version (was llvm-config-2).
 - Reapply of r144300, with lots of fixes/migration easement in between.

Some files installed by clang are not relevant for general users and we'd like
to be able to install them to a different location.  This adds a new
--with-internal-prefix configure option and a corresponding PROJ_internal_prefix
makefile variable, which defaults to the standard prefix.  A tool makefile
can specify that it should be installed to this internal prefix by defining
INTERNAL_TOOL.

build/Make: Switch over to using llvm-config-2 for dependencies one more (hopefully last) time, now that it also builds as a build tool.

case insensitive filesystems, since it contains a "Core" directory.  Since this
is pointless anyway, just zap it.
