It's been there since 908e5310b958619559d34b0b6da122f058faa47e, which
has the commit-subject 'Add a "git-describe" command'.

I think it'd be more trouble removing it now than it is to keep it,
since a lot of script depend on it being there for parsing out
versioning info in various autobuild- and release scripts.

If you want to change it, I'd suggest adding a "--no-sha1" option
that makes the entire "-g%s" part of the output go away, or
perhaps adding a --format="%v-%d-%g" (for the default behaviour).
