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.
