> Currently, if you update a dependency without changing its version, and run {{bin/bootstrap_toolchain.py}}, it won't download the new dependency.
> This is a problem for situations like IMPALA-4983 where we want to change the build flags but don't have a new version number. 
> My suggestion is to use the toolchain build ID as a 'version' parameter, and write that to disk. If the toolchain ID changes, {{bootstrap_toolchain.py}} should detect that case and redownload all dependencies. Although it's suboptimal to download *all* dependencies, it's better than not downloading enough of them.
