The resolve_btfids tool scans elf object for .BTF_ids section
and resolves its symbols with BTF ID values.
It will be used to during linking time to resolve arrays of BTF
ID values used in verifier, so these IDs do not need to be
resolved in runtime.
The expected layout of .BTF_ids section is described in main.c
header. Related kernel changes are coming in following changes.
