Fix out-ouf-source build for runtime as well.
To build out-of-source, follow these steps:
# [[Insert LLVM build instructions here]]
mkdir my_build_dir
cd my_build_dir
svn co http://svn.dsource.org/projects/tango/trunk tango
ccmake <PATH_TO_SOURCE>
# (Regular ccmake stuff, press 'c' a few times followed by 'g')
make
make runtime
# add `PWD`/bin to PATH
closes #213
