This change deletes the pre-DAC versions of the Getting Started and
Programmer's Guide material. The "Start Here" page now directs users to the
NDK docs on DAC, and also points them more explicitly at the offline
documentation for OpenGL, etc., which is still download-only.

This removes a hack for froyo (that didn't really solve the problem even
there), and removes support for gdb versions before 7 (from 2009). If you
really need to work with gdb 6 on froyo, I pity you.

We won't be able to build the Windows LLVM until we get one in the
platform, but that doesn't build right now anyway.

As a side effect, stop building compiler-rt. We get this for free as
part of the prebuilt LLVM.

When building with LLVM, use the platform LLVM.

Note that having ANDROID_BUILD_TOP set is now a requirement. This can
be set manually, by `lunch`, or will be handled by `checkbuild.sh`,
but must be set.

This reverts commit 3975250d.

We *do* use XML target descriptions. This was hidden by the fact that toolchain/build/configure was -- until a later change -- re-adding --with-expat.

I haven't cleaned up the scripts on the assumption that they're all
going the way of the dodo anyway.

We don't actually use any of the things expat gives us:

  https://sourceware.org/gdb/onlinedocs/gdb/Requirements.html

The toolchain repository's copy of expat is out of date, so let's
just drop it.

We don't have ELF TLS (yet), so we don't need a meaningful implementation
of these functions, but gdbserver references these functions directly so
we need some implementation.

* changes:
  Update docs and tools for new branch config.
  Build compiler-rt from the proper directory.

We really need to get away from using a temp directory at all and use
a real out directory, but this is an intermediate step to make us
compatible with what the build server expects.

The master-ndk branch of AOSP now contains an already checked out and
patched version of the toolchain repository at toolchain/. The process
of using download-toolchain-sources.sh is now obsolete. Update the
docs accordingly and remove the obsolete components.

The layout from download-toolchain-sources.sh is a little odd. It
checks out compiler-rt to toolchain/llvm-3.6/compiler-rt and
toolchain/llvm-3.6/llvm/projects/compiler-rt. Building LLVM requires
it to be in the projects directory, so we might as well build
compiler-rt from the same place.

With this change we can actually build the NDK without using
download-toolchain-sources.sh, and instead using the following
manifest changes (still have to run patch-sources.sh until we get a
branch of toolchain/gcc for the NDK and/or get the patch situation
cleaned up):

From Polly's own documentation:

    Even though this example makes it very easy to use Polly, you
    should be aware that Polly is a young research project. It is
    expected to crash, produce invalid code or to hang in complex
    calculations even for simple examples.

There is no sys/procfs.h yet...

This reverts commit 35b7e823.

Mac doesn't have realpath(1), and their mktemp(1) requires a template.

We're trying to get these all submitted properly, but for now let's
keep the NDK building.
