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.

I removed the x86->x86_64 symlink, independent files preferred.

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.
