    added --enable-arm-oabi option to enable it at configure time.

* Improvements
  * Added experimental -k option to print stack trace after each traced syscall.
  * Added -w option to produce stats on syscall latency.
    (addresses Debian bug #457497).
  * Added ARC architecture support.
  * Added PTRACE_GETREGS API support on PowerPC.
  * Enhanced Bionic libc and musl libc support.
  * Enhanced tracing of x86 personality processes on x86_64 and x32.
  * Enhanced tracing of ARM personality processes on AArch64.
  * Enhanced 32/64bit personality detection on PowerPC.
  * Implemented decoding of add_key, ioprio_get, ioprio_set, kexec_load, keyctl,
    renameat2, and request_key syscalls.
  * Robustified decoding of select, pselect, and io_submit syscalls.
  * Enhanced decoding of delete_module, fanotify_init, fanotify_mark, fcntl,
    setdomainname, sethostname, setns, and sync_file_range syscalls.
  * Enhanced decoding of signal bitmasks.
  * Enhanced decoding of file descriptors.
  * Enhanced siginfo_t decoding.
  * Enhanced PF_NETLINK decoding.
  * Updated CLOCK_* constants
    (addresses Fedora bug #1088455).
  * Added new syscall entries to match Linux 3.16.

* Bug fixes
  * Added shmat and shmdt to the set of memory mapping related syscalls.
  * Fixed detaching from stopped processes.
  * Fixed fanotify_mark decoding on 32bit architectures.
  * Fixed offset decoding in preadv and pwritev syscalls.
  * Fixed select decoding for glibc in _FORTIFY_SOURCE mode.
  * Fixed decoding of epoll_ctl syscall with EPOLL_CTL_DEL argument.
  * Fixed build when <sys/ptrace.h> and <linux/ptrace.h> conflict
