The x86 files should actually be removed by make clean. The bug is that
the $(targets) variable must not depend on the configuration, so that
make clean always knows what to delete. I'll send a patch to the x86
maintainers, but such bugs keep creeping in. Other archs possibly have a
similar prolbem.

security/tomoyo automatically generates files that can also be supplied
by the user, which sucks, because make clean does not know whether they
are generated or user supplied.

With git clean and git archive, there is indeed little use for make
distclean. But clean and mrproper should work.
