Martin Jansa 1ceb13dda1 icecc: improve interaction with sstate
* exclude ICECC_PARALLEL_MAKE (like PARALLEL_MAKE is)
* add ICECC_DISBLED to be able to disable whole icecc functionality
  while keeping icecc enabled. This is useful when you want multiple
  builders sharing same sstate-cache, but only some of them using icecc.

* inheriting icecc changes all checksums because of do_*_prepends calls,
  but because icecc should not influence binary output of task we should
  get same checksums for tasks build with and without icecc

* ICECC_DISABLED when set (to any non-empty value will disable icecc env
  modifications but while keeping same sstate checksum
