A better fix here might be possible using the fact that the get_variable()
call allows passing a fallback value in the case of failure. Therefore
something like the below might work cleaner:

foreach d: depends
	static_obj = [get_variable('static_rte_' + d, '']
	if static_obj == ''
		build = false
		reason = '....'
		subdir_done()
	endif
	static_objs += static_obj
...

Maybe a disabler object could be used also.
