You cannot just enable qemu support for an arbitrary MACHINE setting -
you must define your own machine, making sure that you include only
such peripheral support (i. e. drivers) for which emulation under qemu
exists.

When making any significant changes to the configuration, it is
usually best to throw away the whole build tree and restart from
scratch.

Actually this is the most reliable way to make sure you get what you
configured (which may still be different from what you want).

ACK.
