This adds support for the MOVE WITH OPTIONAL SPECIFICATIONS (MVCOS)
instruction. Allow to enable it for the qemu cpu model using

qemu-system-s390x ... -cpu qemu,mvcos=on ...

This allows to boot linux kernel that uses it for uacccess.

We are missing (as for most other part) low address protection checks,
PSW key / storage key checks and support for AR-mode.

We fake an ADDRESSING exception when called from problem state (which
seems to rely on PSW key checks to be in place) and if AR-mode is used.
user mode will always see a PRIVILEDGED exception.

This patch is based on an original patch by Miroslav Benes (thanks!).

Such shifts are usually used to easily extract the PSW KEY from the PSW
mask, so let's avoid the confusing offset of 4.

This is mostly Philippe's updates

We add the following cross-compile targets:
  - mipsel-softmmu,mipsel-linux-user,mips64el-linux-user
  - armeb-linux-user

While I was rolling I discovered we could also back out a bunch of the
emdebian hacks as the newly released stretch handles cross compilers
as first class citizens. Unfortunately this also meant I had to drop
the powerpc support as that is no longer in Debian stable.

Debian has now released Stretch as its new stable. As we track
debian:stable-slim this has a few consequences. For one thing we can
now drop the emdebian hacks as cross compilers are part of the
official repositories now. However we do loose the ability to build
against powerpc (not ppc64) since that is no longer a release
architecture.

Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:

  # lsusb  -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
  Device: ID 1199:9071 Sierra Wireless, Inc.
    idVendor           0x1199 Sierra Wireless, Inc.
    idProduct          0x9071
      bNumInterfaces          5
        bInterfaceNumber        0
        bInterfaceNumber        2
        bInterfaceNumber        3
        bInterfaceNumber        8
        bInterfaceNumber       10

In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.

This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.
