>Description:
mount_nfs does not fall back NFSv2 if kernel does not have
NFSv3 support, so mount_nfs fails on such kernels unless -2 option
is specified.

>How-To-Repeat:
Build kernel with options NFS_V2_ONLY and try mount_nfs on it
from NFSv3 servers:

# mount 192.168.20.1:/home /mnt
mount_nfs: 192.168.20.1:/home on /mnt: Program version wrong
# mount_nfs 192.168.20.1:/home /mnt
mount_nfs: 192.168.20.1:/home on /mnt: Program version wrong
# mount_nfs -3 192.168.20.1:/home /mnt
mount_nfs: 192.168.20.1:/home on /mnt: Program version wrong
# mount_nfs -2 192.168.20.1:/home /mnt
