Having timestamps in gzip leads to lintian warning
'package-contains-timestamped-gzip' and will harm reproducible builds.
Gzip option '-n' avoids saving original file name and especially timestamps
by default.

[seiden@linux.ibm.com: Fix commit message]
Signed-off-by: Steffen Eiden <seiden@linux.ibm.com>
The rust integration into the s390-tools build system consists of the
following steps:
- Add a subdirectory for the rust code.
- Add a Makefile that forwards rust builds to `cargo`.
- Add a `utils` crate for rust code in s390-tools.
- Add rust stuff for dotfiles:
- gitignore
- editorconfig
- codespellrc (while at it, add an ignore file)
With cargo the rust ecosystem has its own build system which also is
responsible to resolve rust dependencies via downloading the dependencies
from (default) crates.io and discover the source files. Therefore, the
Makefile just calls `cargo build` to forward the build to cargo.
If a rust crate does not require external dependencies, users might call
rustc directly.
A simple `make` will build all the rust targets as well (with --release
specified). Also `make install` will work as usual.
A few Makefile configuration variables are introduced for rust/Cargo:
- HAVE_CARGO (default 1) to toggle the build of rust code using cargo
- CARGOFLAGS to add custom cargo flags, e.g. --offline
- CARGO Cargo binary location defaults to
$(where cargo)
A new global make target is defined to get the current s390-tools
version:
$ make version
2.28.0
rust/Makefile also has the `print-rust-targets` target to print all rust
directories/crates that should be shipped/installed.

Commit 62ec87680a61 ("common.mak: improve cross compilation support")
added one extra whitespace during the changes of the toolchain command
definitions. The rest of the commands did not receive that change.
Since then the pretty print output looks like this:
...
CC zipl/boot/eckd1b.o
CXX ziomon/ziorep_collapser.o
SED zdev/src/lszdev_usage.c
CC hyptop/sd_cpu_items.o
MV zfcpdump/zfcpdump-initrd
LINK dasdfmt/dasdfmt
...
Add the additional whitespace to all other tools definitions used during
the build process.
Note: This doesn't fix the misaligned indentation for commands like
$(CC_FOR_BUILD) as those inherit the whitespace from the original
command, here $(CC).

Introduce `BUILD_ARCH` and `(CC|LINK|...|OBJDUMP)_FOR_BUILD` variables
in order to properly support the build of tools that generate code or
data during the build process. Replace existing variables `HOSTCC` with
`CC_FOR_BUILD` and `HOSTCFLAGS` `CFLAGS_FOR_BUILD`. The Makefile
variables for the `HOST_ARCH` are unchanged.

Install libasan first, e.g. on Fedora 32:
dnf install -y libasan libasan-static.
To compile with address sanitizer, pass ASAN=1 to make.
AdressSanitizer helps to catch various memory bugs for which C/C++ is
infamous.

Since version 198 (Feb 2013) systemd contains kernel-install, a script
managing kernel installs. This script allows execution of drop-in scripts
for customization. Add such a drop-in script to s390-tools to handle the
installation of zfcpdump kernels.
It's main purpose is to manage a link to the latest installed zfcpudump
kernel at ZFCPDUMP_IMAGE, where zipl expects to find the image to install
for a SCSI dumper.
The script supports two installation modes. One recommended by the
BootLoaderSpecs [1] to /boot/<machine-id>/<kernel-version> directories and
one directly to /boot. In the second case files are renamed during
installation to <original-name>-<kernel-version> to guarantee unique names.
Because the zfcpdump kernel is so special make the script stand-alone and
prevent any other script from being executed (exit 77) when a zfcpdump is
installed. Especially avoid functionality like creating an initrd (already
provided by s390-tools) or creating a boot entry (the zfcpdump kernel
should not be used for any other purpose than dumping).
The script requires systemd >= 203.

The file system dumper no longer exists. So there is no need in keeping
'PART' to distinguish between the file system and the partition dumper.
Adjust the macro name to the usage in zipl by removing 'PART'.
While at it also adjust the file names the macros stand for.

For systems that do not have glibc-static installed, print the
following error message when building zfcpdump:
s390-tools/zfcpdump # make
REQCHK zfcpdump (stdio.h)
****************************************************************
* Missing build requirement for: zfcpdump *
* Install package..............: glibc-static or libc-dev *

To allow the check add a new compiler/linker option to the "check_dep"
macro and do full compile/link instead of a simple compile.
