[BusyBox] bug#1205: mount handles links differently in 0.60

[David Douthitt]

Package: busybox
Version: 0.60

Given two entries in fstab:

/dev/fd0    /mnt/fd0    [...]
/dev/floppy /mnt/floppy [...]

...and the following files in /dev:

fd0
floppy -> fd0

...then try this sequence with busybox 0.53 and 0.60:

# mount /dev/floppy
# umount /mnt/floppy

...in 0.53, this works.  In 0.60, it fails because the link is
"translated" to /dev/fd0 and is mounted on /mnt/fd0, not /mnt/floppy...
