- Add support to turn off hasing the compiler size and mtime via a
  enviroment variable, this aids in 'buildworld' and 'buildkernel'.

 CCACHE_NOHASH_SIZE_MTIME
    This tells ccache to not hash the real compiler's size and modi-
    fication time. Normally this is the mechanism to detect compiler
    upgrades.  There are situations however, where even  though  the
    compiler's  size or modification time has changed you can safely
    use the cached objects (e.g. if as part of your build system the
    compiler  is  built  as  well  and the compiler's source has not
    changed; or if the compiler has only changes that do not  affect
    code generation). Use this feature only if you know what you are
    doing.
