Allow QEMU to be installed on MIPS targets. Also introduce a new symbol (BR2_PACKAGE_QEMU_ARCH_SUPPORTS_TARGET) to hold the architectures than can build and use QEMU on the target.

QEMU is a generic and open source machine emulator and virtualizer.
|
|
|
|
When used as a machine emulator, QEMU can run OSes and programs made
|
|
for one machine (e.g. an ARM board) on a different machine (e.g.
|
|
your own PC). By using dynamic translation, it achieves very good
|
|
performance.
|
|
|
|
When used as a virtualizer, QEMU achieves near native performances
|
|
by executing the guest code directly on the host CPU. QEMU supports
|
|
virtualization when executing under the Xen hypervisor or using the
|
|
KVM kernel module in Linux. When using KVM, QEMU can virtualize x86,
|
|
server and embedded PowerPC, and S390 guests.
