[PATCH] Fix the build for git repositories with multiple remotes.

[Tim Northover]

>   The handling of the output treats it like a single URL. I'd prefer the first remote since the idea is to tell where you are relative to everyone else, and since the GetSourceVersion script only checks the SVN commit number the remote is what's relevant.

But how's the first remote important? It looks like they're just
sorted alphabetically by their identifiers. I just don't see how the
first in that list is ever a sensible answer to "where did it come
from" except by coincidence.

Cheers.

Tim.
