If you have META_MODE enabled -dM will tell you if meta_oodate
decided the target needs update - and if so exactly why.
Eg. a command changed, a file is updated, missing etc.
If it says nothing, then the target was out-of-date per normal make

If changing any of those knobs impacts CFLAGS etc - then pretty much
everything will be out-of-date.
Adding -dM to your build command should be very instructive.
