I can confirm that. I just set up a build for powerpc with WITHOUT_CLANG
and in the first building steps I saw this.
I don't care if it is only a few minutes of building time, but I
disagree if it is going to be > 10 minutes/hours in case of multilib
builds (32-bit libs and 64-bit libs) as it is on powerpc64. On powerpc64
the WITHOUT_CLANG helped to avoid the build of the multilib.
I do not have anything against CLANG. I only want to be able to steer
what I want.
Gruss,
