Subject: [PATCH] Quicktests: Remove target-OK prior to compilation

Remove target-OK prior to compilation of target with the help of
RULE_LAUNCH_COMPILE. This is a cleaner solution because the removal is only
triggered if target is actually (re)built.

Additionally, reintroduce the ADD_CUSTOM_COMMAND and ADD_CUSTOM_TARGET
splitting so that also quicktests only rerun if they actually have to...
