The zstd library will be automatically linked by detecting the feature libzstd. It is no need to explicitly link it for static builds, so remove the redundant linkage. It is contradictory to detect the feature libelf-zstd while the build configuration NO_LIBZSTD is set. Report an error for reminding users not to set NO_LIBZSTD.
