I just check, and NPTL is enabled. I also did this on the binary I
compiled:

    $ strings  /usr/bin/qemu-sparc32plus-static | grep nptl
    ../nptl/sysdeps/pthread/createthread.c
    ../nptl/pthread_mutex_lock.c
    nptl-init.c
    ../nptl/sysdeps/unix/sysv/linux/x86_64/../fork.c

which suggests that it has been compiled with NPTL.

Title:
  qemu-user-static for sparc32plus : bash: fork: Invalid argument

Status in QEMU:
  New

Bug description:
  On Debian x86-64 host system I setup a sparc chroot using:

  host $ mkdir sparc 
  host $ sudo debootstrap --arch=sparc --foreign wheezy sparc 
http://ftp.au.debian.org/debian
  host $ sudo cp ~/Git/qemu/sparc32plus-linux-user/qemu-sparc32plus 
sparc/usr/bin/qemu-sparc32plus-static
  host $ LANG=C sudo chroot sparc/ /usr/bin/qemu-sparc32plus-static /bin/bash

  When I then run the second stage of debootstrap I get:

  target $ /debootstrap/debootstrap --second-stage
  bash: fork: Invalid argument

  The above procedures works perfectly for armhf.

  This is with current git HEAD (commit
  93b6599734f81328ee3d608f57667742cafeea72).
