So something like

config BR2_PACKAGE_HOST_QEMU_LAUNCH_ARGS
	string "qemu launch command"
	help
	  Command to launch qemu. If this is defined, 'make run-qemu' can be
	  used to build everything and launch qemu.


HOST_QEMU_LAUNCH_ARGS = $(call qstrip,$(BR2_PACKAGE_HOST_QEMU_LAUNCH_ARGS))
ifneq ($(HOST_QEMU_LAUNCH_ARGS),)
run-qemu: world
	$(Q)$(HOST_QEMU) <kernel args> <rootfs args> $(HOST_QEMU_LAUNCH_ARGS)
endif



Looks like a good idea indeed!
