Hi!

After migrating from i386 to x86_64, my uml started to segfault in weird ways.
In the end, I figured that "make clean/mrproper/distclean" does not really
clean up properly. I had to use "ARCH=um make distclean". The command "make
distclean" did not remove these files:

arch/um/include/shared/kern_constants.h
arch/um/include/shared/user_constants.h
arch/um/kernel/config.c
arch/um/kernel/config.tmp
arch/um/kernel/vmlinux.lds
arch/um/sys-x86_64/vdso/vdso.lds
arch/um/sys-x86_64/vdso/vdso.so
arch/um/sys-x86_64/vdso/vdso.so.dbg
arch/um/sys-x86_64/vdso/vdso-syms.lds

Why is this the case?
