Paymon MARANDI 884413b488 build: also consider builds off of git with git clone --depth 1
one case where this could happen is a shallow clone, purely for build
purposes. in source based distros, like gentoo, setting depth of the
clone to 1, globally, is a common configuration. this patch avoids that
those builds fail.
