This adds a new scons flag --no-duplicate-sources to build without linking source files to the build directory. I find this very helpful when using CLion, since I can now generate a compilation database using `bear scons build/ALL/gem5.debug --no-duplicate-sources` and CLion will now correctly semantically analyze all the files inside src/. It also ensures that clicking on a build warning/error now opens the real source file rather than a symlink. This is not enabled by default since it's possible that certain use cases are not working correctly, but the basic testing I've done so far appears to work just fine. It appears that with this change the `<root>/src` directory is no longer added to `PYTHONPATH` when running `tests/main.py`, so this change depends on https://gem5-review.git.corp.google.com/c/public/gem5/+/68757 Change-Id: Iddc9bf9c8211e68e5432c0a07f5c95f427c1ca16 Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/68518 Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Bobby Bruce <bbruce@ucdavis.edu> Maintainer: Bobby Bruce <bbruce@ucdavis.edu>
