Now I see what happened.  I did have a consistent tree, but I was
doing a build via "make ARCH=um O=/usr/projects/linux/uml" --- and I
had previously built a UML tree from another source tree without doing
a "make mrproper", so /usr/projects/linux/uml/include2/asm was a
symlink to another kernel tree's include/asm directory.

It might be nice if kbuild caught the inconsistency, but this was my
bad.
