Unknown git option: -C

I'm trying to compile the latest TensorFlow, but I'm getting a git error:

$ bazel build -c opt //tensorflow/tools/pip_package:build_pip_package
INFO: Loading package: @local_config_xcode//
INFO: Found 1 target...
INFO: From Executing genrule //tensorflow/core:version_info_gen:

           [-c name=value] [--help]
           <command> [<args>]
! 

It looks like the git -C option is used, but that is only supported in git version >= 1.8.

It looks like it's not worth requiring git 1.8 just for this?

@markusdr : Thanks for the note.
We welcome contributions to make this work with git < 1.8 (you probably have to change things in gen_git_source.py. Feel free to submit a Pull Request.

However, given than git 1.8 is over 4 years old, it may be hard to predict other issues that might arise with using very old versions of git. If you consider it particularly important to work with such old versions of git, I'd be curious to hear your thoughts.
