[Qemu-devel] [PATCH 3/4] RFC target/arm: Do not build pre-ARMv7 cpus when using KVM

[Philippe Mathieu-Daudé]

A KVM-only build won't be able to run pre-ARMv7 cpus, disable them.

If KVM is not enabled, they are enabled by default.

Sadly this does not work with --enable-tcg --enable-kvm dual config.
