We already have 2 bbclasses to do that
meta-openembedded/meta-oe/classes/gitpkgv.bbclass
meta-openembedded/meta-oe/classes/gitver.bbclass

there were some plans to get one of them to oe-core, but IIRC it was
decided to create support for this in bitbake fetcher, I'm not sure how
far it went with actual implementation.
