gnu: linux-libre: Enable BTF debug info.
This is needed for software making use of eBPF programs, such as the sysdig utility, among others. For more information about BPF, see: <https://brendangregg.com/blog/2020-11-04/bpf-co-re-btf-libbpf.html>. * gnu/packages/linux.scm (%default-extra-linux-options): Enable CONFIG_DEBUG_INFO, CONFIG_DEBUG_INFO_BTF, CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT, CONFIG_BPF_JIT, CONFIG_BPF_JIT_ALWAYS_ON, CONFIG_BPF_SYSCALL and BPF_UNPRIV_DEFAULT_OFF. Disable CONFIG_DEBUG_INFO_REDUCED. (make-linux-libre*) [native-inputs]: Add dwarves, python-wrapper and zlib. Change-Id: Idfc64f82aa404e86168bffcf721a325f9e807f75
