This DEPS roll is causing "nacl_integration" to fail with:

Exception: Cannot find a toolchain for x86-32 in
/mnt/data/b/build/slave/linux_precise32/build/src/native_client/toolchain/linux_x86/nacl_x86_newlib_raw:
...
  File
"/mnt/data/b/build/slave/linux_precise32/build/src/native_client/site_scons/site_tools/naclsdk.py",
line 100:
    (env['TARGET_FULLARCH'], sdk_path))

Strangely, this is failing on all the trybots that run nacl_integration, but
most of the trybots are ignoring the failure.  I've filed a bug about that:
