aabc632023 bpftools: update to v5.11.16, simplify make
Update to the latest stable upstream version.

Drop unneeded make variables to remove redundant assignments seen during
invocation of package Makefile.

Also remove the following patch now included upstream:

  * 200-fix-install-param-order-on-macos.patch

Compile and run-tested on malta/mips32be, using bpftool directly and also
libbpf (linked with tc) to inspect and load simple eBPF programs.

cf20f1bb5f bpftools: fix feature override for masking clang
Rename feature variable clang-bpf-global-var following upstream changes.
This restores the HAVE_CLANG feature override and should avoid rare build
errors where a recent host clang and BTF-enabled host kernel are present.

c8c638a19b bpftools: drop unneeded libintl linking for NLS
There is no direct linking of libintl from bpftools, only secondary linking
through libelf, so remove "-lintl" from TARGET_LDFLAGS.

9e64e4ce26 bpftools: fix libbpf pkgconfig file
The pkgconfig file hardcodes a host library directory which cannot be
overridden by OpenWrt during builds. Use SED to fix this and potential
include directory problems, as is done with several other packages.

This fixes a strange issue intermittently seen building iproute2 on the
oxnas target:

iptables modules directory: /usr/lib/iptables
libc has setns: yes
SELinux support: no
libbpf support: no
	libbpf version 0.3.0 is too low, please update it to at least 0.1.0
	LIBBPF_FORCE=on set, but couldn't find a usable libbpf

d02088762a build: reorder more BuildPackages lines to deal with ABI_VERSION
After the ABI version rework, packages need to be declared in the order of
their dependencies, so that dependent packages will use the right ABI version

5582fbd613 bpftools: support NLS, fix ppc build and update to 5.8.9
With global NLS support enabled (CONFIG_BUILD_NLS), the linked libelf.so
and libbfd.so libraries will depend on libintl.so. Import the nls.mk helper
to set library prefixes and flags accordingly, and also conditionally add
"-lintl" as link-time library.

Fix a build error on ppc due to a EDEADLOCK redefinition in errno.h.

Use upstream stable kernel 5.8.9, and fix overriding of feature detection
to only allow/hide detected features. Also refresh existing patches.

2f0d672088 bpftools: add utility and library packages supporting eBPF usage
Add support for building bpftool and libbpf from the latest 5.8.3 kernel
sources, ensuring up-to-date functionality and fixes. Both are written to
be backwards compatible, which simplfies build and usage across different
OpenWRT image kernels.

'bpftool' is the primary userspace tool widely used for introspection and
manipulation of eBPF programs and maps. Two variants are built: a 'full'
version which supports object disassembly and depends on libbfd/libopcodes
(total ~500KB); and a 'minimal' version without disassembly functions and
dependencies. The default 'minimal' variant is otherwise fully functional,
and both are compiled using LTO for further (~30KB) size reductions.

'libbpf' provides shared/static libraries and dev files needed for building
userspace programs that perform eBPF interaction.

Several cross-compilation and build-failure problems are addressed by new
patches and ones backported from farther upstream:

  * 001-libbpf-ensure-no-local-symbols-counted-in-ABI-check.patch
  * 002-libbpf-fix-build-failure-from-uninitialized-variable.patch
  * 003-bpftool-allow-passing-BPFTOOL_VERSION-to-make.patch
  * 004-v5.9-bpftool-use-only-ftw-for-file-tree-parsing.patch
