[ccache] cache 3.2.2 calls the compiler with a relative path if CCACHE_BASEDIR is set

Yes, that's a known effect of using CCACHE_BASEDIR, see
https://ccache.samba.org/manual.html#_compiling_in_different_directories:

"The drawbacks of using a base directory are:

* If you specify an absolute path to the source code file, __FILE__ macros
will be expanded to a relative path instead. [...]"
