This patch causes my little-endian microblaze qemu emulations to fail
silently (no console output) in next-20210211. Reverting this patch
together with "scripts: dtc: Build fdtoverlay tool" fixes the problem.

Big endian microblaze emulations are not affected. I can't say if other
emulations are affected because I see too many boot failures in -next
to be able to track down all individual problems.
