We need newer pahole to support `binutils-2.40` which started generating
fresh DWARF tags that pahole-1.24 does not yet understand and fails as:
$ nix log /nix/store/ckjr3sbsh13y1prigppk2y0jpf0p4icm-linux-6.1.6.drv
...
BTF .btf.vmlinux.bin.o
Unsupported DW_TAG_unspecified_type(0x3b)
Encountered error while encoding BTF.
Upstream thread to add the support for it:
