I have seen that before. It happens in buildchroot when using
qemu-arm-static binfmt magic. Something in that chain seems to cause
problems for very long argument lists.
In my case it was a "make clean" and i removed the files from outside
the buildchroot. But since it now happened again it is probably
something worth looking into.
