I honestly don't know how to explain this behaviour either, because it should
not happen this way. BitBake automatically extracts variable references within
variable values and adds them to the dependencies of the variable, so a change
to REV_TOOLS should have resulted in the signatures changing for the do_fetch
tasks for all of the recipes where SRCREV contained the reference and thus all
of those recipes and the ones that depend upon them getting rebuilt.
Did you use oe-init-build-env or oe-init-build-env-memres to initialise your
build environment?
