4e82d99460 libbb/loop: fix existence check for LOOP_CONFIGURE ioctl 
The LOOP_CONFIGURE ioctl is supported in 5.8 kernels and up. To have
backwards compatibility there is a config option CONFIG_TRY_LOOP_CONFIGURE
that will check if the ioctl exists and if not fall back to old way of
configuring loop devices.

Normally errno will be set to EINVAL when this ioctl does not exist.
However, when kernel config CONFIG_COMPAT is enabled, then compat_ioctl
is called. In that case -ENOIOCTLCMD is returned by loop device driver
and generic ioctl wrapper will set errno to ENOTTY. Because busybox
does not expect this it will fail to mount loop devices in this case.

This patch fixes the check for the existence of the ioctl LOOP_CONFIGURE
by checking if errno is one of both: EINVAL or ENOTTY.

6f43f948bc adduser: remove preconfigured GECOS full name field 
Pre-configuring "Linux User" as Full Name is confusing a lot of users
downstream.[1] For example, in geary e-mails were sent out as "Linux
User"[2] and I also saw a couple of git commits with this name. This name
does not bring any more improvements than just leaving this field
empty, and let applications most likely fallback to the username.

Alternative would be to set the field to `&` (Capitalized username,
according to passwd(5)) or that we just set the GECOS field downstream.

993d416d02 md5/sha1sum: Honor the -b flag in the output 
The output of md5sum/sha1sum contains a character to indicate
what mode was used to read the file - '*' for binary, and ' '
for text or where binary is insignificant.

This flag character makes a difference for the ffmpeg testsuite.
This testsuite contains a number of reference files (e.g. [1]),
containing the expected md5sum output for those files, which is
checked verbatim.

By making busybox's md5sum honor this flag in the output,
ffmpeg's testsuite can run successfully on top of busybox.

The flag is only partially implemented; in coreutils md5sum,
a later "-t" option overrides an earlier "-b" option. Here,
just check if a "-b" option was specified or not. Neither
flag affects how the files actually are read.
