A few minor updates based on feedback from Justin and a few things I thought were missing.

* Moved autotools configure & build example out of "Getting Started Quickly (A Summary)" and into BuildingLLVMWithAutoTools.
* Removed the annotations that CMake is the recommended process and Autotools is alternate.
* Added brief documentation about build targets under "Getting Started Quickly..."
* Added Overview text to BuildingLLVMWithAutotools
* Fixed up a broken link.

Overview
========
This document details how to use the LLVM autotools based build system to
configure and build LLVM from source. The normal developer process using CMake
is detailed `here <GettingStarted.html#check-here>`_.
A Quick Summary
---------------
#. Configure and build LLVM and Clang:
* ``cd where-you-want-to-build-llvm``
* ``mkdir build`` (for building without polluting the source dir)
* ``cd build``
* ``../llvm/configure [options]``
Some common options:
* ``--prefix=directory`` --- Specify for *directory* the full pathname of
where you want the LLVM tools and libraries to be installed (default
``/usr/local``).
* ``--enable-optimized`` --- Compile with optimizations enabled (default
is NO).
* ``--enable-assertions`` --- Compile with assertion checks enabled
(default is YES).
* ``make [-j]`` --- The ``-j`` specifies the number of jobs (commands) to run
simultaneously. This builds both LLVM and Clang for Debug+Asserts mode.
The ``--enable-optimized`` configure option is used to specify a Release
build.
* ``make check-all`` --- This run the regression tests to ensure everything
is in working order.
* If you get an "internal compiler error (ICE)" or test failures, see
`here <GettingStarted.html#check-here>`_.

* ``-DLLVM_ENABLE_ASSERTIONS=On`` --- Compile with assertion checks enabled

* Run your build tool of choice!
* The default target (i.e. ``make``) will build all of LLVM
* The ``check-all`` target (i.e. ``make check-all``) will run the
regression tests to ensure everything is in working order.
* CMake will generate build targets for each tool and library, and most
LLVM sub-projects generate their own ``check-<project>`` target.
