As of u-boot-fdt/master commit 503afc3ca1e5 "test: overlay: Add unit
test for stacked overlay", the U-Boot build fails for sandbox with the
error below. I guess it's due to this commit. Does U-Boot now
intentionally rely on a newer dtc or is this an accident?
DTC test/overlay/test-fdt-base.dtb
LD lib/libfdt/built-in.o
CC lib/charset.o
CC lib/rsa/rsa-verify.o
dtc: invalid option -- '@'
Usage: dtc [options] <input file>
Options: -[qI:O:o:V:d:R:S:p:fb:i:H:sW:E:hv]
-q, --quiet
Quiet: -q suppress warnings, -qq errors, -qqq all
