Subject: [PATCH] Tweak build options for faster tool build

Previously building inputmodule-control would be as slow as 20s even
with no code change. Now it takes just less than 1s.

- Remove all options that are default - no need to specify them again.
- Keep the release options the same (Still slow tool build but not as
  important)
- Apply the dev options only to the firmware, not tool
