apparently non-spurious tests/misc/xattr failure with coreutils 8.23

[Nick Alcock]

Here's the FAIL output. (Note that despite the name,
/usr/local/share/compiler-nfs is not nfs-mounted, but is an
xattr-capable ext4 filesystem which I pointed the testsuite at after
getting a similar failure on tmpfs.)

This is with kernel 3.16.3 and libattr current as of commit
55f39ef1ddec924d746d96cbe5bdc1030eeff92b (which is still the trunk
head). Looking at the first failure, it looks like xattrs simply aren't
being properly preserved by cp, even though configure spotted it and cp
is linked against libattr:
