Title:
  O_CLOEXEC not handled in dup3 system call in user mode

Status in QEMU:
  New

Bug description:
  In qemu user mode, for hppa and sparc64 targets, the parameter of the
  dup3 is not passed correctly when it contains the O_CLOEXEC flag.

  When the attached program runs, the expected output is:
  errno=9=EBADF

  How to reproduce on hppa:
  - Compile the program: hppa-linux-gnu-gcc-5 -O -Wall -static testdup3.c -o 
testdup3-hppa
  - Set environment variables for running qemu-hppa.
  - ~/inst-qemu/2.9.0/bin/qemu-hppa testdup3-hppa
  errno=22=EINVAL
  testdup3.c:54: assertion 'errno == EBADF' failed

  How to reproduce on sparc64:
  - Compile the program: sparc64-linux-gnu-gcc-5 -O -Wall -static testdup3.c -o 
testdup3-sparc64
  - Set environment variables for running qemu-sparc64.
  - ~/inst-qemu/2.9.0/bin/qemu-sparc64 testdup3-sparc64
  errno=22=EINVAL
  testdup3.c:54: assertion 'errno == EBADF' failed
