Currently, xdp-tools doesn't compile on build systems where
bpftool is installed because additional tools and BPF programs
will be compiled then, which results in build errors.
This commit disables the compilation of those bpftool-dependent tools.

To enable verbose log for xdp-tools compilation, we check for "c" in
the OPENWRT_VERBOSE, but verbose.mk supports only "w" and "s" for V=1
and V=99.
Fix the wrong matching and correctly enable verbose output matching for
"s".

Currently it's needed to have gcc-multilib on the host to correctly
compile xdp-tools. This is wrong and means that we are using host header
to compile a tool.
By some searching in how the makefile works it was discovered that
BPF_CFLAGS were not used and required to be appended to config.mk
Only one single header was added but we should include each BPF_CFLAGS
from bpf.mk. To make this some patching to bpf-header were required and
some patches to xdp-tools were required.
Also it's needed to pass the correct target to BPF_CFLAGS.
With the following changes xdp-tools can correctly compile with each
header from bpf-headers and should not use any host header.

When building xdp-tools with CONFIG_USE_LLVM_HOST=y, on a host that
enabled stack protector by default in Clang, compilation fails with the
following error:
CLANG xdp-dispatcher.o
clang-16: error: ignoring '-fstack-protector-strong' option as it is not currently supported for target 'bpfeb' [-Werror,-Woption-ignored]
Add -fno-stack-protector to BPF_CFLAGS to fix this.

Based on Paul Fertser <fercerpav@gmail.com>'s guidance:
Change AUTORELEASE in rules.mk to:
```
AUTORELEASE = $(if $(DUMP),0,$(shell sed -i "s/\$$(AUTORELEASE)/$(call commitcount,1)/" $(CURDIR)/Makefile))
```
then update all affected packages by:
```
for i in $(git grep -l PKG_RELEASE:=.*AUTORELEASE | sed 's^.*/\([^/]*\)/Makefile^\1^';);
do
make package/$i/clean
done
```

xdp-tools build currently breaks on build hosts which do not have
libbpf headers installed because the build system wrongly tries to
use the host's include path.
Properly pass path to libbpf headers to xdp-tools build system to
fix build e.g. on the buildbots.

Make sure the 'configure' shell script finds the libintl when linking
the test programs for discovering libpcap and libbpf.

The SDK does not have the LLVM toolchain yet.
Hopefully fixes errors in the form:
