acpi-build: disable with -no-acpi
QEMU will currently crash if started with -no-acpi flag since acpi build code probes the PM device which isn't present in this configuration. To fix, don't expose ACPI tables to guest when acpi has been disabled from command line. Fixes LP# 1248854 https://bugs.launchpad.net/qemu/+bug/1248854 Reported-by: chao zhou <chao.zhou@intel.com> Signed-off-by: Michael S.
