It should be possible to set SKIP_FILEDEPS per package, not just per recipe. I did a trivial implementation of this once, but the margins of this bug report are too small to contain it. Mostly filing this for tracking purposes, I could probably do that implementation again and submit it later.
Bumping to 1.7 since I never got around to it. I still want to do this.
