Remove autoconf support

Summary:
This patch is provided in preparation for removing autoconf on 1/26. The proposal to remove autoconf on 1/26 was discussed on the llvm-dev thread here: http://lists.llvm.org/pipermail/llvm-dev/2016-January/093875.html

    "This is the way [autoconf] ends
    Not with a bang but a whimper."

-# We don't currently support building runtime libraries when we are
-# cross-compiling. The issue is that we really want to be set up so that the
-# available compiler targets are independent of the current build.
-#
-# Since we have to build the runtime libraries for the target, it requires we
-# have a cross compiler from the build machine to the target. Although in the
-# case where for the current build (host == target), we do have such a cross
-# compiler, but not defined in a way that is easy for us to reuse. Regardless,
-# that also wouldn't help for other possible compiler configurations.
-#
-# Thus, the simple set up we currently use is to assume that we will be using
-# the just built Clang to compile the compiler-rt libraries. As we grow better
-# cross compilation support inside Clang and tool support in LLVM, this makes it
-# easier for us to achieve the goal of having the compiler targets be easily
-# selected at configure time. However, this design does currently preclude the
-# building of compiler-rt libraries when the Clang itself is being cross
-# compiled.
-#
-# There are three possible solutions:
-#  1. Require building a build-target version of Clang when cross compiling. This
-#     is simplest, but als greatly increases the build time of cross builds.
-#
-#  2. Require cross builds have a build-target version of Clang available for
-#     use. This is a reasonable compromise on #1, as the compiler-rt libraries
-#     are simple enough that there is not a strong desire to ensure they are
-#     built with the exact version of Clang being used. Similarly, as Clang
-#     becomes a better cross compiler it is also increasingly more likely that
-#     the cross compiler being used will already be a version of Clang.
-#
-#  3. Come up with an alternate mechanism to define all the toolchain
-#     information that compiler-rt would need to build libraries for all the
-#     requested targets. This might be a simple short term solution, but is
-#     likely to be unwieldy and irritating to maintain in the long term.
