This commit fixes a segmentation fault in Binutils dlltool that occurred when using the --exclude-symbols option. The crash was a regression introduced by a previous commit that did not account for how dlltool processed symbol names with leading underscores during option handling. The fix modifies the string_list structure and related functions (add_excludes, underscore_excludes) to properly manage memory for excluded symbols, especially regarding potential leading underscores, restoring stable operation.
