The responsible code for stripping is in line 2843 in config.cpp. The
whole substitution process seems a little bit awkward and fixing it
might be more involved.

NB: To add a config variable you need to add it to the config.xml file
and not to the configoptions.cpp file. Don't forget to rerun
configgen.py. It is really unfortunate that the file is commited and not
generated during the build process.
