remove code that embeds the build path Embedding the build path (BUILD_DATA_DIR, BUILD_CONFIG_DATA_DIR) into the binary makes the build unreproducible. The small check was only needed for running supertux from within the source directory. As this does not make sense for the distributed packages, this can be safely removed. If you are working on the code and need to run supertux from the source directory, either set SUPERTUX2_DATA_DIR or unapply this patch.
