There are a lot of failures there, though none seem to be all that serious for real-world use. Probably the best thing to do is to go through them one by one. The first failure is in tests/tail-2/F-vs-missing.sh, and the log says:
+ rm -rf /data/prj/gnu/coreutils/coreutils-8.20/gt-F-vs-missing.sh.f7EB rm: cannot remove '/data/prj/gnu/coreutils/coreutils-8.20/gt-F-vs-missing.sh.f7EB': File exists This indicates that coreutils 'rm -rf' somehow missed some files under that directory, and then tried to remove the directory without removing the files, or perhaps the kernel didn't remove the files, or something like that. Can you please 'truss' the test and see what system calls were executed near the point of failure? One way to do that would be something like this: cd tests truss -f -o /tmp/tr make check TESTS=tail-2/F-vs-missing.sh and then look near the end of /tmp/tr.
