Created attachment 5032 patch for config.guess and config.sub Support for the ARM 64 bit CPU architecture (aarch64) was introduced in autoconf 2.69. thunar-archive-plugin appears to use an earlier version of autoconf, preventing its being built. Please regenerate config.guess and config.sub with autoconf 2.69 or apply the attached patch.
