pahole --btf_encode_detached doesn't export all the global variables

[gcmoreira]

Unless I'm missing something, it seems like pahole --btf_encode_detached doesn't export all the global variables

$ ../pahole_git/build/pglobal -v vmlinux-5.8.0-53-generic | sed '/^$/d' | wc -l
26843

$ ../pahole_git/build/pahole --btf_encode_detached vmlinux-5.8.0-53.btf vmlinux-5.8.0-53-generic
$ ../pahole_git/build/pglobal -v vmlinux-5.8.0-53.btf | sed '/^$/d' | wc -l
90

$ cd ../pahole_git
$ git rev-parse --short HEAD
