[4/4] RFC target/arm: Do not build A/M-profile cpus when using KVM

Commit Message

Philippe Mathieu-Daudé Aug. 23, 2019, 1:58 p.m. UTC

A KVM-only build won't be able to run A or M-profile 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.

Likewise as for the previous patch, "depends on TCG".
