It appears that scons bugs are not on tigris.org any more and are now on github, although fortunately old bugs seem to have been ported over and have the same numbering. This CL updates URLs which were in comments in the gem5 source, specifically in scons scripts, to point to the corresponding github version. I also checked to see if these bugs were still open, or if we could remove our workarounds for them. 1. 2356 is still open, and has been fairly recently assigned. 2. 2611 is marked as fixed. We might be able to implement the workaround in its last comment from August of 2019. 3. 2811 has been marked fixed, and as best I can tell the fix first appeared in around version 3.0 of scons. If/when that is our minimum version, we can remove the workaround in site_scons/site_tools/default.py. That is mostly fixing an annoying spurious rebuild by scons which does not affect correctness, so even if we remove that workaround we shouldn't break earlier versions, although it would be obnoxious for people that are affected by it and best avoided.
