I might be wrong, but NO_CLEAN seems like a bad idea except in special
circumstances. Install ccache, but make sure you set
CCACHE_HASH_COMPILER environment variable to 1. That will make sure
that the cache stays valid if the compiler executable is overwritten
by an identical copy (as it would be on installworld). When the
compiler changes the cache will be repopulated on the next rebuild.
