ldattach: don't compile for non-linux systems
There is just ldattach which doesn't compile because line disciplines are not
implemented that way on the Hurd. Is TIOCSETD any kind of standard? Else I
guess the patch below would be fine.

umount: improve "-d" option for autoclear loops
The new loop auto-destruct feature detaches automatically loop devices
when no longer used. This means they are detached with the umount()
call. But when we call umount with -d, del_loop() is called and fails
because the ioctl() returns ENXIO. We have to check for autoclear
loop devices rather than blindly call del_loop().

mount: warn on "file_t" selinux context
Currently if I mount a file system without labels, it works fine, but
later or SELinux will start printing denials and stopping certain
applications from working. It would be nice if the mount command
checked it in selinux mode.

hwclock: always reads hardware clock
It's a pity that hwclock first tries to read the clock when running
hwclock --systohc --noadjfile --utc
and exits as this fails. I cannot see a reason to read first in that
case.
Old version:
# hwclock --systohc --noadjfile --utc --debug
hwclock from util-linux-ng 2.14
Using /dev interface to clock.
Assuming hardware clock is kept in UTC time.

This patch allows "tolerant" behavior, i.e. proceeding even if
priority could not be set. This might be of use in case something
(selinux, old kernel, etc.) does not allow the requested scheduling
priority to be set.
This could be to some extend done as follows:
ionice -c3 command || command
but the downside is that one could not really tell if what failed was
setting priority or command itself, which could result in duplicate
command run.
This patch solves the situation, so that user can do
ionice -t -c3 command

more: dont use a.out.h
The a.out.h header is not friendly to portable systems (iow, those that
lack a.out support), and since the defines are only used in a cheesy magic,
just use the magic constants. It's not like they're ever going to change.

mount: remount doesn't care about loop=
The command
# mount -oremount <spec> <dir>
doesn't read fstab or mtab. This is expected behaviour. Unfortunately,
we have to care about the internal loop= option which is generated and
maintained by mount(8)/umount(8). The loop= option has to be persistent.
How to reproduce this bug:
# mount -o loop /home/images/vfat.img /mnt/img; grep vfat /etc/mtab; \
mount -o remount,ro /home/images/vfat.img /mnt/img; grep vfat /etc/mtab;
