Buildroot 2022.05 use binutils 2.37 by default, but the binutils
version was downgraded to the previous binutils version in qemu_ppc64*
defconfigs due to a bug in binutils 2.37 [1].
Later when binutils 2.36 has been removed the binutils version has
been updated to 2.38 (even though it was already the default version
selected by Buildroot at that time) [2].
Since then, several binutils release has been added and the binutils
version 2.38 has been removed recently [3].
Since the initial bug is gone with the removal of binutils 2.37,
we can safely remove the binutils version from qemu_ppc64 defconfigs.

Commit 1e2fe860f3 (configs/qemu_ppc64*: downgrade binutils to 2.36.1).
Since then, we've dropped support for binutios 2.36, and hte default is
2.38.x, which has the required changes to fix:

Pin the qemu-ppc64 defconfig to explicitly use binutils 2.38.x

[yann.morin.1998@free.fr:
- explictily force binutils 2.38
- reword commit log to explain why
- reword commit log: it's not really a revert

ppc64 or powernv Linux defconfig fail to build with gcc 11 and/or
binutils 2.37 [1] :
CC kernel/kexec_file.o
Cannot find symbol for section 10: .text.unlikely.
kernel/kexec_file.o: failed
Patches have been sent upstream and should reach Linux 5.18. Until
then, limit binutils to 2.36.1 which doesn't raise the issue.

PowerNV is the platform using the OPAL [1] firmware on OpenPOWER
systems. OPAL first loads a kernel and an initramfs image based on
buildroot including a second boot loader petitboot [2]. The latter
does device discovery and kexecs a new Linux image from disk or
network.
QEMU implements PowerNV machines [3] for the POWER8, POWER9 and
Power10 processors which are used for dev and tests. POWER8 images
being compatible with POWER9 and Power10, simply add a single
qemu_ppc64le_powernv8 board for all.
The QEMU script boots directly from a nvme disk because it is simple
enough but a real system would boot from a ramfs first.
