The answer changes if you have more than one buildhost. If you have only one
buildhost and don't care about other people rebuilding the exact same
versions, 1.0+git${SRCPV} will work.

If you have more than one buildhost and/or care about other people
rebuilding the exact same, you'll need to increase PR (or PV) everytime
SRCREV changes. That will still cause some discrepancies if someone rebuilds
after >1 SRCREV change, but upgrade paths should work when increasing PV
(not with PR!).
