* exec/configure.ac (OPEN_SYSCALL, OPENAT_SYSCALL): Define new
macros.
* exec/exec.h (struct exec_tracee): New field `sp'.
* exec/trace.c (handle_openat): New function.
(process_system_call): If handle_openat executes successfully,
save the unmodified stack pointer within the tracee structure to
be restored once the system call completes.

It’s not worth the porting hassle, and as the glibc manual says,
“this function is generally a poor choice for processing strings”.
* admin/merge-gnulib (GNULIB_MODULES): Remove stpncpy.
* exec/configure.ac: Do not check for stpncpy.
* exec/exec.c (rpl_stpncpy, stpncpy): Remove this replacement.
(exec_0): Properly clear buffer1. Use memcpy instead of
stpncpy to add the trailing name. This code is clearly
still suboptimal but efficiency is not that important here
and I tried to minimize the change.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

* exec/config.h.in: Autoheader.
* exec/configure.ac: Check for siginfo_t.si_syscall.
* exec/trace.c (exec_waitpid): If SIGSYS is received, and caused by
seccomp, drop it should the call number be the invalid system call
used by Emacs.

* exec/config.h.in: Autoheader.
* exec/configure.ac: Use system extensions.
(HAVE_PROCESS_VM): Define if process_vm_readv and
process_vm_writev are available.
* exec/trace.c (read_memory, user_copy): Implement in terms of
process_vm if possible.

* exec/config.h.in (__bool_true_false_are_defined):
* exec/configure.ac (REENTRANT): New definition.
(READLINKAT_SYSCALL, READLINK_SYSCALL): New defines. Set on all
hosts.
* exec/exec.c (MIN, MAX): Remove redundant declarations. Move
to config.h.
(exec_0): Copy name of executable into NAME when !REENTRANT.
* exec/exec.h (struct exec_tracee): New struct `exec_file'.
* exec/trace.c (remove_tracee, handle_exec, handle_readlinkat)
(process_system_call, after_fork): Handle readlinkat system
calls.

* exec/configure.ac: Check for declarations of stpcpy and
stpncpy.
* exec/exec.c (stpcpy, stpncpy): Use replacements if
declarations are not present; this happens when a new Android
NDK is building for an old version of Android.

* Makefile.in (extraclean): Clean in exec as well.
* configure.ac: Fix detection of absolute srcdir. Also, pass
CFLAGS.
* exec/Makefile.in: (.c.o): Add -I. so config.h can be
found.:(.s.o): Don't create m4 temporary in srcdir.

to substitute if as cannot assemble daddi.
* exec/configure.ac (user_h): Look for user.h in asm/ as well.
Use new user.h. Also look in ptrace.h on arm systems. Check if
as supports daddi on mips64.
