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.
