There are cases where users do VPATH builds with the source directory being on a read-only volume. In such a case they have to manually run the command 'git-submodule.sh ...modules...' ahead of time. When checking for status we should not then write into the source dir. Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
