USE_GITHUB and submodules

[Jonathan Anderson]

Thanks everybody for the input! With a security hat on, I definitely
concur with the policy of no fetching outside of fetch and of requiring
reproducibility/verifiability (e.g., commit hashes). With my
getting-this-darn-port-updated hat, however... :)

I think that I'll try to go with Shane's solution, if others concur that
it's a good idea. I don't want to create a rust-llvm port, since Rust's
customized version of LLVM isn't much good outside of Rust, it doesn't
expose any external libraries and it's intended to eventually go away.
So, until GitHub implements the "give me a tarball with all of the
submodules" feature, I might try hacking up MASTER_SITES as Shane suggests.

Cheers,


Jon
