Old CPU models are not officially supported anymore by IBM, and for
downstream builds of QEMU, we would like to be able to disable these
CPUs in the build. Thus add a CONFIG switch that can be used to
disable these CPUs (and old machine types that use them by default).

If you're interested, the PDF that can be downloaded from
https://www.ibm.com/support/pages/ibm-mainframe-life-cycle-history
shows the supported CPUs in a nice diagram
z13 is still supported so the patch needs to be fixed at least.
Oh, drat, I misread the diagram, indeed. 'should have looked at the table
instead :-/
Furthermore, z14 has the IBC/VAL cabability to behave like a z13,
same for z15. (we do support VAL to N-2)
Hmm, so if z13 is still supported, and also has the possibility to do N-2,
I assume the z114/196 and z12 should still be considered as non-legacy, too?
