I haven't seen anyone run into this in a long time. :)

In this case, it is likely one of two things:

+ Look at your $PATH. Make sure the RTEMS tools are first.

+ But in your case, I expect that it is because the clang didn't
know (somehow) to put the target name in front of the as.
Did you invoke it for sparc-rtems5? If so, then there is a
path through clang where it isn't looking at the target name.

I also double checked the as manual to ensure -Av8 was in
fact a sparc option.
