When building a kernel with LLVM and CONFIG_DEBUG_INFO_BTF after commit
32ef9e5054ec ("Makefile.debug: re-enable debug info for .S files") in
the kernel, I see the following spew of warnings, which appear to come
from pahole:
die__process_unit: DW_TAG_label (0xa) @ <0x7b> not handled!
die__process_unit: tag not supported 0xa (label)!
die__process_unit: DW_TAG_label (0xa) @ <0x97> not handled!
die__process_unit: DW_TAG_label (0xa) @ <0xbd> not handled!
die__process_unit: DW_TAG_label (0xa) @ <0xed> not handled!
die__process_unit: DW_TAG_label (0xa) @ <0x109> not handled!
die__process_unit: DW_TAG_label (0xa) @ <0x12a> not handled!
die__process_unit: DW_TAG_label (0xa) @ <0x146> not handled!
die__process_unit: DW_TAG_label (0xa) @ <0x16f> not handled!
To fix this issue, backport dwarves upstream patch:
dwarf_loader: Support DW_TAG_label outside DW_TAG_lexblock

Also upgrade bundled libbpf to commit 393a058, the same as what's
designated in upstream submodule commit.
Introduce a patch from upstream commit 73383b3a3 to avoid using
deprecated libbpf APIs.
