Subject: [PATCH] ccache 3.2.1 -> 3.2.2

New features and improvements:
- Added support for "CCACHE_COMPILERCHECK=string:<value>". This is a faster
  alternative to "CCACHE_COMPILERCHECK=<command>" if the command's output
  can be precalculated by the build system.
- Add support for caching code coverage results (compiling for gcov).

Bug fixes:
- Fixed bug which could result in false cache hits when source code contains
  '"' followed by " /*" or " //" (with variations).
- Made hash of cached result created with and without "CCACHE_CPP2"
  different.  This makes it possible to rebuild with "CCACHE_CPP2" set
  without having to clear the cache to get new results.
- Don't try to reset a non-existing stats file. This avoids "No such file or
  directory" messages in the ccache log when the cache directory doesn't
  exist.
- Fixed a bug where ccache deleted clang diagnostics after compiler
  failures.
- Avoid performing an unnecessary copy of the object file on a cache miss.
- Bail out on too hard compiler option "-fmodules".
- Bail out on too hard compiler option "-fplugin=libcc1plugin" (interaction
  with GDB).
- Fixed build error when compiling ccache with recent clang versions.
- Removed signal-unsafe code from signal handler.
- Corrected logic for when to output cached stderr.
- Wipe the whole cached result on failure retrieving a cached file.
- Fixed build error when compiling ccache with recent clang versions.
