There is also the issue of Doxygen being ran from the main project Makefile (I put it there so that the input paths in the Doxyfile would be defined relative to the root of the coreboot tree), which causes the top level `build` directory to be created (as well as some other subfiles/subdirectories). This is an issue in the container as the coreboot tree is mounted read only.
