If you use bitbake-1.10 it will do it just once for git revision (it
will cache the result of "git list-rev | wc -l" which is used by
BB_GIT_CLONE_FOR_SRCREV.

No they won't be the same. They will have the same format
git${LOCALCOUNT}+${HASH} as when AUTOREV+SRCREV is used.

Check "[oe] SRCPV migration - How SRCPV works!" thread for more info

in short: why do you insist on BB_GIT_CLONE_FOR_SRCREV? autoincremented
LOCALCOUNT works good in most cases (as long as you keep cache dir), only 
case for which we introduced BB_LOCALCOUNT_OVERRIDE is for multiple builders 
sharing feed, but not cache directory.
