Yeah. To clarify my earlier comment: what Salesforce did[1] was basically
to modify the configure script to do this automatically. That meant that
even a heavily-hacked development build would still advertise itself as
having an identifiable commit hash. I think that leads to at least as
much confusion as value added.
The only way that something like this can have any integrity is if the
hash is added in an automated, hands-off build process that works only
from clean git pulls. The approach Michael suggests works just fine as
part of a build script that's used that way. But I doubt that it's wise
to put it somewhere where the hash could end up in hand-modified builds.
