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.

Fix: bpftools 5.11.2 does not compile on macOS, because the -m option
was placed between src and dst. Corrected by moving -m 644 before src.

Use the latest stable kernel since the previous 5.8.x series is EOL.
Also drop the following patches recently accepted 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

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.

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
