It appears to be trying to use unlinkat. Now, looking at the 
versioning symbols in glibc 2.5, this would appear to have been 
introduced in g libc 2.4. unlinkat is a proper syscall and ... it was
only introduced into the kernel fairly recently. So they may 
not have added it to the ARM kernel. I vaguely remember reading 
on the armlinux mailing list that the *at functions are either 
unimplemented or they've only been added recently. coreutils appears
to contain some utility functions in the lib directory which 
implement the *at functions for platforms that don't support it. 
Now I'm guessing either libc hasn't properly identified that the 
*at functions don't work on this platform and compiled them in a
syscalls. Or coreutils hasn't properly identified that the *at 
functions don't work on this platform.

Make a build log. grep it for unlinkat
