5259a39c7a configs/qemu_mips64r6: fix Linux kernel build with gcc 10.x
From [1]

"GCC 10 (PR 91233) won't silently allow registers that are not architecturally
available to be present in the clobber list anymore, resulting in build failure
for mips*r6 targets in form of:
...
.../sysdep.h:146:2: error: the register ‘lo’ cannot be clobbered in ‘asm’ for the current target
  146 |  __asm__ volatile (	 \
      |  ^~~~~~~

This is because base R6 ISA doesn't define hi and lo registers w/o DSP extension.
This patch provides the alternative clobber list for r6 targets that won't include
those registers."

Since kernel 5.4 and mips support for generic vDSO [2], the kernel fails to build
for mips r6 cpus with gcc 10 for the same reason as glibc.

7dcb9e98b5 board/qemu: remove the Qemu version from readme.txt
The Qemu version present in readme.txt files was needed when
the Buildroot's Qemu defconfig was tested manually using the
qemu-system-<arch> binary already present on the host.

This information is now incorrect since we are using host-qemu
package, currently at 4.2.0 version, to do a runtime test since
0c79350638.

For m68k-q800, we can use the upstream qemu since 4.2.0 release
[1].

So, remove this line from the readme.txt.

011206b2bf board/qemu: add defconfig file name as tag after the qemu command line
This commit add the name of the Qemu defconfig file after each
qemu command line in order to retrieve it easily.

Since a readme.txt can be shared between several Qemu defconfig, we
need at least one qemu command line in readme.txt for each defconfig.

For now, ignore the qemu_arm_vexpress_tz_defconfig since it fail to build
due to python script issue [1]. Anyway the arm vexpress boot is tested
with qemu_arm_vexpress_defconfig.

626c9705d2 board/qemu: ensure root is available before mounting it
On my machine, it happens once in a while that the virtualised machine
boots too fast for the rootfs to be available at the time the kernel
tries to mount it.

For example, board/qemu/arm-vexpress/readme.txt suggested changing
"-smp 1" up to "-smp 4". But doing so here causes a kernel panic:

    VFS: Cannot open root device "mmcblk0" or unknown-block(0,0): error -6
    Please append a correct "root=" boot option; here are the available partitions:
    1f00          131072 mtdblock0
     (driver?)
    1f01           32768 mtdblock1
     (driver?)
    Kernel panic - not syncing: VFS: Unable to mount root fs on
    unknown-block(0,0)

So, add the oh-so-useful 'rootwait' option to all kernel command lines
for qemu defconfigs.

28d97609b2 configs/qemu: bump to the latest kernel version
Xtensa patches no longer required, the make target name changed
to Image. The Qemu binary for OpenRisc was renamed upstream.
I removed the x86->x86_64 symlink, independent files preferred.

(1) - Probably an endian issue with 8139 emulation/driver
(2) - There's a network interface, but enabling it in qemu fails
(3) - Known to fail with qemu versions lower than 2.6.0
(4) - Might work with 2.6.0, but the cpu definition changed in 2.7.0
