As PTRACE_POKEUSER is crippled on x32 by design from the very first
linux kernel commit v3.4-rc1~33^2~2 when it was introduced,
workaround this by using the raw x86_64 syscall instead.
* linux/ptrace_pokeuser.c: New file.
* linux/x32/ptrace_pokeuser.c: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* upoke.c: Include "ptrace_pokeuser.c".

Move the code than deals with updating the return and error values
to separate functions.
* syscall.c (set_error, set_success): New functions.
(tamper_with_syscall_exiting): Use them.
* linux/*/get_error.c: Rename all arch-specific implementations
of get_error() to arch_get_error().

(tamper_with_syscall_exiting, get_syscall_result): Do not clear
tcp->u_error before get_error() invocation as the latter does it now.
The test already expects a ", " before the print of struct
padding. Let's add it to s390.c to make the output look a bit nicer and
fix test runs on z/VM that have padding at the end of the STHYI structs.
* s390.c (decode_ebcdic): Add missing comma.

When the first exec fails, strace used to print the trace of the child
process till its end, producing a lot of confusing output.
Enhance the diagnostics by hiding irrelevant parts of the trace.
