up to ccache 3.1.9

Release date: 2013-01-06

Bug fixes
~~~~~~~~~

    - The EAGAIN signal is now handled correctly when emitting cached stderr
      output. This fixes a problem triggered by large error outputs from the
      compiler.
    - Subdirectories in the cache are no longer created in read-only mode.
    - Fixed so that ccache's log file descriptor is not made available to the
      compiler.
    - Improved error reporting when failing to create temporary stdout/stderr
      files when executing the compiler.
    - Disappearing temporary stdout/stderr files are now handled gracefully.

Other

    - Fixed test suite to work on ecryptfs.
