Vitor Massaru Iha ca3a2ca4cf um: ensure make ARCH=um mrproper removes arch/$(SUBARCH)/include/generated/ 
commit 63ec90f18204f2fe072df108de8a021b28b1b173 upstream.

In this workflow:

$ make ARCH=um defconfig && make ARCH=um -j8
  [snip]
$ make ARCH=um mrproper
  [snip]
$ make ARCH=um defconfig O=./build_um && make ARCH=um -j8 O=./build_um
  [snip]

make[1]: Leaving directory '/home/iha/sdb/opensource/lkmp/linux-kselftest.git/build_um'
make: *** [Makefile:180: sub-make] Error 2

The cause of the error was because arch/$(SUBARCH)/include/generated files
weren't properly cleaned by `make ARCH=um mrproper`.
