The ABI doesn't change between builds of the same source tree which is why there are no actual rebuilds ("CC") of all modules. But your usage of bindeb-pkg bumps the version string (also without CONFIG_LOCALVERSION_AUTO) and this needs to end up in each module file which explains the LD/BTF/SIGN/INSTALL steps. [..]
