The core emulated by default by qemu-mips(el) just crashes with illegal instruction when encountering DSP and/or MIPS16e instructions - we have to specify a CPU that supports the extra instructions. This is an issue when generating a rootfs and e.g. running some of the package postinstall scriptlets. The patch to qemu to add 24KEc as a CPU has been accepted upstream, so let's use that CPU here as well as needed.
