If this is the last part of the make -k check .... output: Glibc's check (almost) always ends this way.
There's a handful of known (and sometimes unknown...) errors that can occur, that is why the grep Error glibc-check-log needs to be executed and the result compared with what is mentioned in the book.
If you come across errors that are not mentioned, you need to check the log file to determine if these are time-out related (one possible solution for those errors is given in the book).
Without knowing what the grep Error ... command produces, nothing can be said about the above.
Hope this helps.
