Currently, addr2line.c defines SHF_COMPRESSED as 0 if not defined. This is problematic because this results in treating sections as not compressed even if they really are. If not defined, SHF_COMPRESSED should be defined as (1 << 11) instead. A patch is attached for that.

@xtkoba (Tee KOBAYASHI) Can you give me an example of a specific environment where this would be an actual problem? I can't verify this.
