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

The DEBUG macro is not part of any compiler standards (differently from
NDEBUG, which elides assertions).
It is only meant to differentiate gem5.debug from .fast and .opt builds.
gem5 developers have used it to insert helper code that is supposed to
aid the debugging process in case anything goes wrong.
This generic name is likely to clash with other libraries linked with
gem5. This is the case of DRAMSim as an example.
Rather than using undef tricks, we just inject a GEM5_DEBUG macro
for gem5.debug builds.

The code in util/systemc was moved into a subdirectory recently. The
scons support here referred to it, and needed to be updated.

* Use one SConstruct to build everything instead of one SConstruct for
each example.
* Introduce SConscripts for sub-directories.
* Build in 'build' instead of the source tree.
* Build and link to SystemC from the ext/systemc directory. This
ensures that SystemC does not need to be installed on the host and
avoids possible issues caused by an incompatible SystemC build.
* Update the README and add some minor fixes
