Patch [1] caused building util/m5 to fail due to the flag was not an option in the SConstruct file. It is apparently the case for other programs in util/ relying on scons. This patch fixes the above problem, and also adheres to the default behavior introduced by [2]. [1] This patch introduced the "--no-duplicate-sources" flag to the scons build in util/ https://gem5-review.googlesource.com/c/public/gem5/+/68518 [2] This patch turns this flag off by default, https://gem5-review.googlesource.com/c/public/gem5/+/69717 Change-Id: I51376f7b3bf06438b7bc7ff84bc599deecac5bd1 Signed-off-by: Hoa Nguyen <hoanguyen@ucdavis.edu> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/69797 Maintainer: Bobby Bruce <bbruce@ucdavis.edu> Reviewed-by: Alex Richardson <alexrichardson@google.com> Tested-by: kokoro <noreply+kokoro@google.com> Reviewed-by: Ayaz Akram <yazakram@ucdavis.edu>
