*	bpftools: support NLS, fix ppc build and update to 5.8.9	Tony Ambardar	2020-09-18	6	-33/+72
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	bpftools: add utility and library packages supporting eBPF usage	Tony Ambardar	2020-08-31	5	-0/+508
	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 Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
