Description
(from https://github.com/rust-lang/backtrace-rs/issues/410#issuecomment-832871699)
It would be really nice to see support for .gnu_debugdata, which contains compressed symbol tables. For example, the elfutils command eu-readelf --elf-section -s file... can read this.

Research direction
The issue names no repository files or tests. Start by examining how backtrace-rs currently reads ELF symbol tables, then compare the expected .gnu_debugdata contents with eu-readelf and the linked GDB documentation. Done means backtrace-rs can use compressed symbol tables from .gnu_debugdata.
