>Description:

Since the recent update of the emulators/qemu package to version
2.5.0, it no longer builds on NetBSD 6.1.5.

The build fails with:

  hw/misc/ivshmem.o: In function `pci_ivshmem_realize':
  /usr/pkgsrc/emulators/qemu/work/qemu-2.5.0/hw/misc/ivshmem.c:976: undefined reference to `shm_open'
  /usr/pkgsrc/emulators/qemu/work/qemu-2.5.0/hw/misc/ivshmem.c:983: undefined reference to `shm_open'

>How-To-Repeat:

  cd /usr/pkgsrc/emultors/qemu
  make

>Fix:
