Heiko Carstens 9e89f4de79 selftests: vDSO: fix vdso_config for s390
[ Upstream commit a6e23fb8d3c0e3904da70beaf5d7e840a983c97f ]

Running vdso_test_correctness on s390x (aka s390 64 bit) emits a warning:

Warning: failed to find clock_gettime64 in vDSO

This is caused by the "#elif defined (__s390__)" check in vdso_config.h
which the defines VDSO_32BIT.

If __s390x__ is defined also __s390__ is defined. Therefore the correct
check must make sure that only __s390__ is defined.

Therefore add the missing !defined(__s390x__). Also use common
__s390x__ define instead of __s390X__.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
