Pseudo code: make install, modules-install etc. depend on other targets if and only if there are multiple targets on the command line. A bare make install will have no dependencies on vmlinux, make install plus other targets will wait for the other targets. Mind you, I still think that removing the dependency to avoid root turds is the wrong approach.
goal := $(sort $(MAKECMDGOALS)) goal_install := $(filter %install,$(goal)) goal_other := $(filter-out %install,$(goal)) ifneq ($(goal_install),) ifneq ($(goal_other),) $(goal_install): $(goal_other) endif endif
