[Buildroot] [PATCH 0/30] QEMU on the target (branch yem/target-qemu)

Hello All!

After too long a time in limbo, here is a respin of my series about
running QEMU on the target.

Having QEMU on the target can be usefull in more cases than one might
expect Buildroot to catter for:

  - deploy a brand new system on a new board, but with a legacy
    application that only runs on DOS, Windows. After some feedback,
    this happens more often than we would think; legacy DOS applications
    are legions, and as is often the case for those antiquated type of
    software, source code and specifications are long lost, so it is not
    possible to re-build the application.

  - for the same reason, a new design that uses a different architecture,
    but still requries such a legacy (obviously Linux) application to
    still run. qemu-user can come handy in those cases.

  - in some systems, it is better to completely isolate untrusted parts
    of an application in a VM, even at the cost of performance, as a VM
    provides almost-complete isolation.

  - coupled with libvirt (to come in a future patchset), we can build a
    very lightweight system to host VMs.

Currently, we make QEMU only available on x86 (32-bit or 64-bit), as
that's what it was tested with. QEMU is also supposed to run on a PPC,
that can be added later on by an interested party.

Regards,
Yann E. MORIN.
