Removing a hook script and building, script still present

[Kyle Nitzsche]

I had a snap/hooks/prepare-slot-serial-port hook script and built the snap.

I then realized I did not want the hook, so I deleted the file and re-ran snapcraft.

The final snap still contained the hook script, so I had to clean and build, which took a long time since this is building a a gadget on pi3.

Expected behavior: snapcraft would detect a previous hook script is no longer present and create a new snap without it, without needed to clean first.

unrelated to this bug report, why exactly do you build pi gadgets on a pi? all our pi gadgets should be cross buildable by design (unless foundations broke this very recently) by simply using snapcraft --target-arch={armhf|arm64}

@Ogra: I've sensed (perhaps incorrectly) a lack of full-bore support for cross compiling and thought it was a straighter path to build natively.

[Oliver Grawert (ogra)]

it is definitely the less exercised and less tested path ... same goes for kernel snaps btw ...

[Kyle Nitzsche (knitzsche)]

@which is less tested/exercised: native build, or cross compile?
