RC_2_0 Python bindings build with b2 is broken

[ichorid]

When trying to compile Python bindings with the recommended python setup.py build process, compilation crashes immediately with an error: error: Could not find a Jamfile in directory '../../deps/try_signal'.

Full log:

you need the submodules to build, specifically deps/try_signal. Run:

git submodules update --init --recursive
