Use arch of the analizer machine instead of the original one.

When creating the content of the ctu-dir the target architecture was
used to which compilation happened. If the analysis runs on a different
architecture (e.g. for debugging reasons) then the analyzer can't find
the necessary files of which the paths are named after the architecture.
