[Qemu-devel] [PATCH v2] configure: Support QEMU cross-compiling for ARM64 host

[Anup Patel <anup.patel@linaro.org>]

We should be able to configure QEMU for cross compiling it for ARM64 host.

This patch only tries to make sure that the configure step falls through 
and atleast QEMU cross-compilation starts.

The rationale behind cpu=aarch64 naming (as commented by Peter Maydell):
For the target architecture name (ie what comes out in the
qemu-foo and qemu-system-foo binary names) we generally use
the same name that 'uname -m' produces on those machines. In
this case that would be "aarch64".
