PATCH 1/3 board/qemu/ppc64le-pseries: use qemu-system-ppc64

qemu-system-ppc64le doesn't necessarily exist: it isn't installed by Qemu, and only created as a symlink to qemu-system-ppc64 by some distributions (Ubuntu). Other distributions (Fedora) just have qemu-system-ppc64.

But qemu-system-ppc64 is capable of running little-endian PPC64 systems, so use this one instead.

PATCH 2/3 board/qemu/ppc64le-pseries: put Qemu command on one line

This allows the toolchain building machinery used by
https://toolchains.bootlin.com to automatically re-use this Qemu command line.

PATCH 3/3 board/qemu/ppc64le-pseries: make Qemu command similar to ppc64-pseries

In reply to Thomas Petazzoni

In particular:

- Explicitly specify the CPU to be used, POWER8, which matches qemu_ppc64le_pseries_defconfig

- Use hard disk emulation to access the root filesystem instead of an initrd.
