When calling variadic functions, NULL must be explicitly cast to a
desired type.
This is noted in the exec(3) manpage.
The call in newgrp.c was changed for consistency.

Since aarch64 kernel can be configured with compat 32-bit support
enabled, extend translation rules in a way similar to x86/x86_64.

On architectures without special personalities setarch uses the contents
of a local variable with automatic storage duration after return from
the function, causing it to report a spurious error.

The big-endian version maps generic "ppc" and "ppc32" aliases to
PER_LINUX32. It seems that we can do the same for little-endian.
Note that SYS_personality does not care about LE/BE, it's 32 or 64 bit.

Remove global variable, skip unnecessary comparison, and remove version
printing function when a simple printf() can do the job. In same go fix
compiler warning.

Consolidate --help and --version descriptions. We are
now able to align them to the other options.
We changed include/c.h. The rest of this patch was
generated by sed, plus manually setting the right
alignment numbers. We do not change anything but
white spaces in the --help output.

Depending on architecture and kernel version, personality
syscall is either capable or incapable of returning an error.
If the return value is not an error, then it's the previous
personality value, which can be an arbitrary value
undistinguishable from an error value.
To make things clear, a second call is needed.
For more details about personality syscall peculiarities see

When the provided string does not match any architecture that
setarch knows about, the response stays "Unrecognized architecture",
but when trying to set the specified architecture does not have any
effect, then respond with "Kernel cannot set architecture to...".

Use two separate strings for the two different forms of setarch,
instead of filling in an untranslated word into a single string.
Also use the standard angular brackets for nonliteral arguments.
