LFS has a page that has all the build logs
(this is pentium based, there's also a amd based directory), I don't know if CLFS has a simular page or that the LFS page can be used.
The annexc errors you encounter is mentioned in the LFS document and can be safely ignored. The tst-time.out error is probably execution time related (as jayjwa already mentioned).
If the make step ran without stopping with an error, I do believe that these 2 errors can be ignored and you can continue building your CLFS.
PS: The glibc-check-log contains all the output the make check command created, you can take a look in there and see what happened (the lines before the actual error message).
Hope this helps.
