Subject: [PATCH 4/5] LoongArch: Enable debug information in defconfig

There exists the following error when building bpf selftest:

  $ cd tools/testing/selftests/bpf/
  $ make
  ...
  libbpf: failed to find '.BTF' ELF section in /home/fedora/bpf.git/vmlinux
  Error: failed to load BTF from /home/fedora/bpf.git/vmlinux: No data available

Enable CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT and CONFIG_DEBUG_INFO_BTF
to avoid the building errors.
