Tests build time on non-trivial OE build.
Uses hardcoded git revisions of each layer, to make it reproducible.
For the test scripts and README.md how to run them see the branches for each OE branch, most available results are from 'zeus', but zeus isn't supported anymore for a while and it won't be compatible with recent distributions on host. You can always add buildtools tarball or run it inside some container, but that might affect the build time as well, so use it only if you plan to run your OE builds that way as well.
