ccache: updated to 3.7.6

ccache 3.7.6

Bug fixes
The opt-in “file_macro sloppiness” mode has been removed so that the input \ 
file path now is always included in the direct mode hash. This fixes a bug that \ 
could result in false cache hits in an edge case when “file_macro \ 
sloppiness” is enabled and several identical source files include a relative \ 
header file with the same name but in different directories.

Statistics files are no longer lost when the filesystem of the cache is full.

Bail out on too hard Clang option -MJarg (in addition to the previous bailout of \ 
-MJ arg).

Properly handle color diagnostics in the depend mode as well.
