message: Update README.md with instructions on how to perform a full build with the WASM toolchain

  By default LLVM and clang do not include the WASM build target, so you will have to build it yourself. Note that following these instructions will create a version of LLVM that can only build WASM targets.
  ```
  -git clone --depth 1 --single-branch --branch release_40 git@github.com:llvm-mirror/llvm.git
  +mkdir ~/wasm-compiler
  +cd ~/wasm-compiler
  +git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/llvm.git
  cd llvm/tools
  -git clone --depth 1 --single-branch --branch release_40 git@github.com:llvm-mirror/clang.git
  +git clone --depth 1 --single-branch --branch release_40 https://github.com/llvm-mirror/clang.git

  mkdir build
  cd build

  +### Using the WASM compiler to perform a full build of the project
  +
  +The WASM_LLVM_CONFIG environment variable is used to find our recently built WASM compiler.
  +This is needed to compile the example contracts insde eos/contracts folder and their respective tests.
  +
  +```
  +git clone https://github.com/eosio/eos --recursive
  +mkdir -p eos/build && cd eos/build
  +WASM_LLVM_CONFIG=~/wasm-compiler/llvm/bin/llvm-config cmake ..
  +make -j4
  +```
