integrity after download.

Bug fixes:

- Fixed a bug which could lead to false cache hits for compiler command lines
  with a missing argument to an option that takes an argument.

- ccache now knows how to work around a glitch in the output of GCC 6's
  preprocessor. (This was supposed to be fixed in 3.2.6 but wasn't.)
