Since commit [1], the MMU support is mandatory for MMU-capable ARM
cores. This includes the arm926t ARM core used the
qemu_arm_versatile_nommu configuration.
From [2]
"I don't think supporting ARMv5 noMMU makes much sense, as
explained in the commit log. Supporting ARMv7-M definitely makes
sense, but not ARMv5 noMMU."
Remove this defconfig.
