[FeatureRequest] Allow building in non-HG repositories.

[Stefan Marr]

Hi:

For a while, I have the work-around below in my copy of the Graal repository to enable building in a git-based environment.

Would it be possible to integrate something along those lines?
I guess, currently it is also not possible to build graal without errors from a simple source tarball.
For me, upstreaming this would make it easier to test against the latest version of Graal.

Thanks
Stefan
