In a bug comment you said that adding `-fdebug-prefix-map` worked around most of them, but in the example you added the option using `--with-extra-cflags`. This option is supposed to be added automatically anyway, so you observing a difference when explicitly adding the flag leads me to believe there is some difference in options when you enable ccache.
