From 7235d88103dca52d41da3abe0d6513db9a09b193 Mon Sep 17 00:00:00 2001

Subject: [PATCH] externalgitsrc: changed so that the variable is now only set
 once instead of beeing read every time its assigned.

This also rebuilds recipes which use the EXTERNALSRC_GIT_SRCREV variable, when the variable changes.
