The current test had a few fall-outs: - it was checking only for T (.text) symbols - did not consider symbol removal Fix that by fetching all the symbols and doing a bidirectional check - for added and removed symbols. Error out with informative message for each case. v2: Rebase on top of $NM patch. Signed-off-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Daniel Stone <daniels@collabora.com>
