Doesn't work with ccache installed, but then after reinstalling ccache to check its version, I can't reproduce it anymore, go figure :-\
Can you guys please take a look at tmp.perf/fixdep in my tree and check that the last two patches are the ones that should go upstream and that you are able to build it _with_ ccache installed?
Thanks,

Checking ccache version _after_ reinstalling it. [acme@jouet linux]$ rpm -q ccache ccache-3.3.3-1.fc25.x86_64
Before removing ccache:

Even if I try removing the build directory it fails:
