This isn't perfect as the scripts can still fail if only certain filters are disabled. This is still an improvement as now "make check" has better behavior when all encoders or decoders are disabled. Grepping ../config.h is simple and fairly clean but it only works if config.h was created. CMake builds don't create config.h but they don't use these test scripts either. Thanks to Sebastian Andrzej Siewior for reporting the problem. Thanks to Jia Tan for the original patch which grepped xz error messages instead of config.h.
