Ah, OK.

I've tried to reproduce
http://autobuild.buildroot.net/results/8e8/8e8fd1e19d6d07212f29e19a305712e715fe781b//
on gcc20 where the error occurred, just to rule out any build machine
specific issue. Building just cjson+tinycbor worked fine.

I've done restarted the full configuration of build
8e8fd1e19d6d07212f29e19a305712e715fe781b, to see if it helps
reproducing the build failure or not. If it doesn't, then we clearly
have a parallel build issue.

I'll keep you informed of the result (if I don't forget). Ping me if
you don't have news tomorrow evening :)

Thanks!

Thomas
