A bit of a pitty that they don't automatically disable building this
tool, or something like that, but fair enough.

This commit points to just wiring the syscall on the s390 architecture,
which is not really "that" important, so I changed the reference to
e6cfc0295c7d51b008999a8b13a44fb43f8685ea instead (which also appeared
in 3.14, so it doesn't change the rest of the patch).

Applied with that change. Thanks!
