-fstack-protector-strong is controlled by the in-tree
CONFIG_STACKPROTECTOR_STRONG config option. If the flag is set without
the config option, scst fails to build:
ERROR: modpost: "__stack_chk_fail" [scst/src/scst.ko] undefined!
-fstack-clash-protection is disabled in the kernel's Makefile due to an
incompatibility with randomize_kstack_offset.

Support for the following changes in the Linux kernel v6.12:
- 5f60d5f6bbc1 ("move asm/unaligned.h to linux/unaligned.h")
- cb787f4ac0c2 ("[tree-wide] finally take no_llseek out")
This patch fixes the installation process for Linux kernels where the
default value of INSTALL_MOD_DIR differs from `extra`.
For instance, it unbreaks `make rpm` against Fedora's kernels, where
INSTALL_MOD_DIR is set to `updates`.
1. Correct a typo, changing `make release` to `make 2release`.
2. Add information about package-related targets to the help section.
3. Remove `dev_handler` directory during the uninstall process.
4. Eliminate the non-existent `tgt` target from the PHONY targets.
5. Introduce SCST_MOD_DIR and SCST_DH_MOD_DIR as helper variables.
The line in /lib/modules/4.19.0-18-amd64/build/Makefile on Debian 10 with
the path to the header files is as follows:
MAKEARGS := -C /usr/src/linux-headers-4.19.0-18-common O=/usr/src/linux-headers-4.19.0-18-amd64
while on Debian 11 the contenst of /lib/modules/5.10.0-8-amd64/build/Makefile
is as follows:
include /usr/src/linux-headers-5.10.0-8-common/Makefile
Add support for extracting the header file directory path from the Debian
10 Makefile.

Decide which SCSI header file to include based on a compile time check instead
of trying to derive that choice from the UEK kernel version.

Apparently the UEK 8 FC patches have been ported to UEK 7. Make fcst build
against the latest UEK7 and UEK 8 kernels. This patch breaks compatibility
with older UEK 7 5.4.17 kernels.

r9586+r9587 added support for UEK 8 but broke support for UEK 7. Since as
far as I know no compile-time constants are available in UEK that allow to
tell the difference between the UEK 7 and UEK 8 5.4.17 kernels, extract the
UEK release number from the name of the directory with the kernel build
infrastructure.

This patch fixes the build against UEK kernel 5.4.17-2136.300.7.el8uek and
breaks the build for older 5.4.17 UEK kernels, e.g.
5.4.17-2102.200.13.el8uek.

Remove this occurrence because it is not necessary and because checkpatch
complains about it.

The previous commit removed support for building with clang. Restore support
for building with clang without breaking cross-compilation support.

$(KBUILD_EXTRA_SYMBOLS) is not only used at compile time but also at link
time. Move the $(KBUILD_EXTRA_SYMBOLS) definitions such that it is
available both at compile time and at link time.

While $(src) is always defined, $(KBUILD_EXTMOD) is only defined when
building code as an external module.

Copying Module.symvers is the oldest supported method for building external
kernel modules that depend on another external kernel module. Since support
for that method will be removed from Linux kernel v5.5, use
KBUILD_EXTRA_SYMBOLS instead to specify the external symbols SCST kernel
modules depend on. Support for KBUILD_EXTRA_SYMBOLS was introduced in
upstream kernel v2.6.26 so this patch drops support for kernels before
v2.6.26.
