scons: Remove a workaround for a very old SCons bug.
I can't conclusively verify that this issue has been fixed because I
can't find any information about it on the internet. It's "SCons bug
2006" and "gem5 bug 308" but neither project still uses whatever bug
tracking mechanism those numbers correspond to. The change was mentioned
in the gem5 code base at least as early as 2008, and so hopefully has
been fixed in the last 13 years. I did a clean build without this
workaround, and things seem to work.
