Po Lu 6b5accdc05 Port seccomp acceleration to Linux 3.5.0 
* 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.

README 

This directory holds the source code to a library used to replace the
`execve' and `execveat' system calls, used by the Android port of
Emacs to start executables without intervention from the system.

The most edifying resource for developers will be GDB, or to be precise,
the Linux target implementations for architectures of interest.
