Subject: [PATCH v2 0/2] tools/nolibc: support for 32-bit s390

Support for 32-bit s390 is very easy to implement and useful for
testing. For example I used to test some generic compat_ptr() logic,
which is only testable on 32-bit s390.

The series depends on my other series
"selftests/nolibc: test kernel configuration cleanups".
(It's not a hard dependency, only a minor diff conflict)
