s390: Enable VDSO for static linking
Although s390 only enables vDSO for dynamically linked elf binaries
(arch/s390/kernel/vdso.c:217), there is no indication in the code or
associated commit message for why not enable it for statically linked
binaries as well. To double check, I rebuilt a kernel with the
check removed and the vDSO does work for static build for supplied
symbols.
Checked on s390x-linux-gnu and s390-linux-gnu.
[BZ #19767]
* sysdeps/unix/sysv/linux/s390/init-first.c: Remove #ifdef SHARED.
* sysdeps/unix/sysv/linux/s390/libc-vdso.h: Likewise.
* sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h
(ALWAYS_USE_VSYSCALL): Define.
* sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h
(ALWAYS_USE_VSYSCALL): Likewise.
