Although I didn't, this patch should Cc the maintainer of
./scripts/headers_install.sh.  I thought this should be as a separate
one, but I can Cc (in the commit message) to the commit that actual
build happens if that helps to understand.

The standalone UML doesn't use the headers_install.sh script (AFAIK),
so I think this would be okay.
