759	Incremental build is broken	Jakub Jermář	Jiří Zárevúcky	"Incremental build is severely broken. Steps to reproduce:

  1. build default amd64 profile
  1. apply the patch below that should result in HelenOS hanging early during boot
  1. type `make` and watch how only libc gets rebuilt
  1. run HelenOS and watch how HelenOS continues to run normally
  1. now do `make clean; make`
  1. only now the change takes effect and HelenOS hangs as expected

The patch for testing:
