Log Message:
ccache 3.3.4:

New features and improvements:
* Documented the different cache statistics counters.

Bug fixes:
* Fixed a regression in ccache 3.3 related to potentially bad content of \ 
dependency files when compiling identical source code but with different source \ 
paths. This was only partially fixed in 3.3.2 and reverts the new “Names of \ 
included files are no longer included in the hash of the compiler’s \ 
preprocessed output” feature in 3.3.
* Corrected statistics counter for -optf/--options-file failure.
* Fixed undefined behavior warnings in ccache found by -fsanitize=undefined.
