Most of it was present inside buildroot/output.* and the rest scattered
on top level.
This came about for the n-th time when we were reviewing QEMU trace file
locations.
On one hand, it would be cool to have per arch traces.
This made buildroot/output.${arch}~/ a natural choice.
But on the other, those traces have nothing to do with Buildroot,
and could potentially interfere with Buildroot build files.
It also feels nicer to have buildroot/ pristine source code only,
and keep all output under a single directory out/
