If the kernel contains commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3,
both PTRACE_PEEKDATA and process_vm_readv become unavailable when the
process dumpable flag is cleared. As the first 4 syscall arguments are
still available via registers, do not treat this as get_syscall_args
error.
This condition is triggered and therefore tested by prctl-dumpable test.
* linux/mips/get_syscall_args.c (get_syscall_args) [LINUX_MIPSO32]:
Do not bail out if umoven fails.
If the kernel contains commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3,
PTRACE_PEEKTEXT becames unavailable when the process dumpable flag is

if PTRACE_PEEKTEXT fails.
This condition is triggered and therefore tested by prctl-dumpable test.
* linux/sparc64/get_scno.c (arch_get_scno): Do not bail out
if PTRACE_PEEKTEXT fails.
Move is_negated_errno() to a separate new header file negated_errno.h
and include it just for architectures which require it.
is_negated_errno() is not used on those architectures
that have a dedicated register to signal a syscall error.
The issue was raised when compiling with clang, which is more
strict regarding semantics of unused static inline functions
defined in C files and will issue a -Wunused-function warrning
if they are not used anywhere.
* syscall.c (is_negated_errno): Move to ...
