[Qemu-devel] [PATCH v6 08/24] target-arm: Disable 32 bit CPUs in 64 bit linux-user builds

[Peter Maydell <peter.maydell@linaro.org>]

If we're building aarch64-linux-user then the 32 bit CPUs are
all unwanted, because they can't possibly execute the 64 bit
binaries we will be running; disable them.
