It won't matter, I am using my own repo [1] and didn't update/rebase
against master since it was working. I've just cloned and rebuilt it
again now, and I got no such error. I suspect Tuaz is missing
something. Tuaz, It maybe helpful if you provided full details how you
set up the toolchain and RTEMS with configuration options, and full
error log.
