* etc/NEWS: Update correspondingly.
* exec/Makefile.in (config-mips.m4): Don't define rule
or predicate $(LOADOBJS) on it elsewhere than on MIPS.
* exec/README: Direct developers to GDB.
* exec/trace.c (finish_exec): Resume the tracee after reporting
an error in `exec'.
(after_fork): If seccomp is enabled on Android, and the kernel
is 4.7 or earlier, detect whether revisions to the sequencing of
seccomp events have been backported from 4.8.
(exec_waitpid): Resume the process with PTRACE_CONT after
receiving an unknown signal.
(exec_init): Cease disabling seccomp on Android kernels earlier
than 4.8.
* exec/Makefile.in (is_mips): New substitution.
(.s.o): Avoid calling m4 unless it be set.
* exec/configure.ac: Substitute is_mips, and don't generate
config-mips.m4 otherwise.
* exec/loader-x86.s:
* exec/loader-x86_64.s: Use assembler rather than m4-defined
comment syntax.
* exec/Makefile.in (.SUFFIXES): Include ., then `srcdir'.
* exec/loader-aarch64.s (_start):
* exec/loader-armeabi.s (_start):
* exec/loader-mips64el.s (__start):
* exec/loader-mipsel.s (__start):
* exec/loader-x86.s (_start):
* exec/loader-x86_64.s (_start): Get basename of opened exec
file and make it the command name. Fix envp skipping on x86
and various leaks.
* 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.
* exec/config-mips.m4.in (DADDI2, DADDI3): New macros. Define
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.
* exec/exec.c (check_interpreter): Fix char signedness bug.
* exec/loader-mips64el.s (__start): Use DADDI2 and DADDI3 for
two- and 3-operand daddi.
* exec/mipsel-user.h: Don't include sgidefs.h.
* java/INSTALL: Document that m4 is now required.
* src/android.c (android_rewrite_spawn_argv): Add missing NULL.
