`df /some/mount-point' no longer hangs when an unrelated hard-mount
is unavailable
[__GLIBC__]: GNU libc's statvfs stats each mount point in
/proc/mounts until it finds one with matching device number. This is
unnecessary when the FILE argument *is* a mount point. No stat call
is necessary in that case. So, disable the statvfs-testing code on
systems with GNU libc. Reported by Andrei Gaponenko via Tim Waugh
as RedHat bug# 84846.
