[Buildroot] RFC: "make emu" build and start QEMU target

[Spenser Gilliland]

Hi,

I'm proposing a project where a "make emu" target would be added to
Buildroot in order to start a virtualized version of the target.  This
would provide developers with the ability to quickly test and validate
their configuration.

To configure the emu target a new top-level menu, "Target Emulation,"
would be added.  This menu would contain the following options.

Emulation Method -> QEMU
QEMU Version -> Custom Git Tree | Custom tarball | Custom Version | X.Y.Z
... Source Configuration similar to Kernel ...
Machine -> list of machines
Memory -> Memory in Megabytes
Additional QEMU Options -> (additional options for command line)

This will start the qemu-system-$(ARCH) version of QEMU with the
appropriate configuration.

Thanks,
Spenser
