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. Fixes: 2f0d672088 ("bpftools: add utility and library packages supporting eBPF usage") Signed-off-by: Tony Ambardar <itugrok@yahoo.com>

+Subject: [PATCH] tools/arch/powerpc: fix EDEADLOCK redefinition errors in
+ errno.h
+
+A few archs like powerpc have different errno.h values for macros
+EDEADLOCK and EDEADLK. In code including both libc and linux versions of
+errno.h, this can result in multiple definitions of EDEADLOCK in the
+include chain. Definitions to the same value (e.g. seen with mips) do
+not raise warnings, but on powerpc there are redefinitions changing the
+value, which raise warnings and errors (with "-Werror").
+
+Guard against these redefinitions to avoid build errors like the following,
+first seen cross-compiling libbpf v5.8.9 for powerpc using GCC 8.4.0 with
+musl 1.1.24:
+
+ In file included from ../../arch/powerpc/include/uapi/asm/errno.h:5,
+ from ../../include/linux/err.h:8,
+ from libbpf.c:29:
+ ../../include/uapi/asm-generic/errno.h:40: error: "EDEADLOCK" redefined [-Werror]
+ #define EDEADLOCK EDEADLK
+
+ In file included from toolchain-powerpc_8540_gcc-8.4.0_musl/include/errno.h:10,
+ from libbpf.c:26:
+ toolchain-powerpc_8540_gcc-8.4.0_musl/include/bits/errno.h:58: note: this is the location of the previous definition
+ #define EDEADLOCK 58
+
+ cc1: all warnings being treated as errors
+ make[5]: *** [target-powerpc_8540_musl/bpftools-5.8.9/tools/build/Makefile.build:97: /home/kodidev/openwrt-project/build_dir/target-powerpc_8540_musl/bpftools-minimal/bpftools-5.8.9//libbpf/staticobjs/libbpf.o] Error 1
