The horrendous downsides of this are:
* It is likely preventing <<ccache>> hits when building to different output paths, because it makes the `-I` includes point to different paths. This is especially important for <<gem5-ruby-build>>, which could have the exact same source files as the non-Ruby builds: https://stackoverflow.com/questions/60340271/can-ccache-handle-symlinks-to-the-same-input-source-file-as-hits
* when <<debug-the-emulator,debugging the emulator>>, it shows you directories inside the build directory rather than in the source tree
* it is harder to separate which files are <<gem5-code-generation,generated>> and which are in-tree when grepping for code generated definitions
