Stefan Liebler 434fe1a409 S/390: Fix layout of struct sigaction_t
The ordering of some fields in  struct sigaction on s390x (64bit)
differs compared to s390 and other architectures.
This patch adjusts this order according to the definition of
<glibc-src>/sysdeps/unix/sysv/linux/s390/bits/sigaction.h

Without this fix e.g. the call
sigaction( suspendSignalNumber, &sigusr1, null ) in thread.d
leads to setting the sa_restorer field to 0xffffffffffffffff.
In case a signal, the signal handler returns to this address
and the process stops with a SIGILL.

This was observable in several execution testcases on s390x:
libphobos.druntime/core/thread.d
libphobos.druntime_shared/core/thread.d
libphobos.thread/tlsgc_sections.d
libphobos.allocations/tls_gc_integration.d
libphobos.phobos/std/parallelism.d
libphobos.phobos_shared/std/parallelism.d
libphobos.shared/host.c
libphobos.shared/linkD.c
libphobos.shared/linkDR.c
libphobos.shared/link_linkdep.d
libphobos.shared/load.d
libphobos.shared/loadDR.c
libphobos.shared/load_linkdep.d
libphobos.shared/load_loaddep.d

and Phobos library.

DRuntime is the low-level runtime library backing the D programming
language, hosted at https://github.com/dlang/druntime/.

Phobos is the standard library for the D Programming Language, hosted
at https://github.com/dlang/phobos/.

The following sources and directories are part of DRuntime:

To report a bug or look up known issues with the runtime or standard
library please visit the issue tracker at https://issues.dlang.org/.

All changes to either of these libraries should go through the
upstream repository first, then merged back to GCC.
