You also do not want this, because this hurts performance badly.

No. This is the state of affairs.

There is a proposed solution
.NOTINTERMEDIATE:

You can use it like this
.NOTINTERMEDIATE: %.h %.d hello.z
This will cause %.d %.h and hello.z files to not be treated as intermediate.

See https://savannah.gnu.org/bugs/?60297.
If you can build make yourself you can apply the patch attached to
this proposal.
