couple different ways to do this. this is the quickest. another would be to
generate the asm file to pass lint but never use it. i got confused reading
through the build file when gen_config lint_config and gen_rtcd_header didn't
all contain the same things. lint_config and gen_rtcd_header could probably be
collapsed because lint takes the same first argument as gen_rtcd

I think this is fine for now.
