This may or may not help, but Dir('.') in the SConscript dir will,
when stringified, give '.' while reading the SConscript, but 'A/B'
during the actual build, because the path is relative to the current
dir at that time, and when a SConscript it being read, its dir is the
cwd, but when building, top is always the cwd.  So if you can delay
converting Dir('.') to a path until build time, it should just work.
