I can *NOT* reproduce the issue on Debian stretch (gawk 4.1.4, make 4.1).
Also, here the .deps/ directory is not being generated by make -qp.


Back to Debian unstable / Arch / Fedora 30.

I tested with good old wget and see the same issue.
The command sequence is
  git clone https://gitlab.com/gnuwget/wget.git
  cd wget
  ./bootstrap
  cd gnulib
  git checkout master
  git pull
  cd ..
  git commit -m "update gnulib" gnulib
  ./bootstrap
  ./configure
  make syntax-check

This also creates the .deps/ directory. So maybe make 4.2.1 has a bug as
it creates files though -q is given. But then, why can't you reproduce
with the same version of make ?

Earlier in this thread I attached a Dockerfile that makes it pretty easy
to reproduce. If you don't use docker, I could send you the complete
make -qp output.
