Kbuild: Introduce QEMU_PIPE option
If set, 'make qemu' will direct its console output to a named pipe and disable the interactive monitor. Intended for use with the new sanity check system which will parallelize test execution. Change-Id: I902f77c02ed3f210891ff13147afea890e64d9c1 Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
