Setting up new platforms to handle emulation, and make them the only ones able to run on QEMU from the Makefile "qemu" target to avoid confusion with other platforms. We have now platform qemu_x86 and platform qemu_cortex_m3, also modification to the sanity checks to have qemu support only on those platforms Signed-off-by: Sergio Rodriguez <sergio.sf.rodriguez@intel.com> Change-Id: I9291918a1d58fea4f37750ada78234628f9a5d98 Signed-off-by: Anas Nashif <anas.nashif@intel.com>
