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.

ppc-mpc8544ds: switch to custom kernel config since the new 4.3-shipped
mpc85xx_basic_defconfig doesn't work with Qemu.
Incidentally while cleaning it up it now seems to work fine with newer
qemu versions.
sparc64_sun4u: ditch ne2k driver since it's useless, and add the e1000
driver which works fine.
x86: stick to 4.2.x kernels since 4.3 doesn't work right with uclibc
(any variant) based toolchains.

Tweak the configs to deal with b155f5a5ab
fallout.
And bump to the latest kernel versions.
As of this commit the microblaze qemu targets seem broken, probably
because of commit 14e527eb66 or some qemu
limitation.
SPARC seems to have issues as well, the kernel seems to go down with an
unhandled exception with qemu 1.7.0
