[Joel Rosdahl]

Bug fixes:

  - Fixed a bug introduced in 4.4 where ccache could produce false direct cache
    hits in some situations if it decides to disable the direct mode
    temporarily (e.g. due to “too new header” file).

Test improvements:

  - Use shell builtin pwd command for basedir test.

  - Cope with CC being a wrapper script that uses ccache.
