The previous approach uses readelf -DWs, which does not produce a stable output format (older binutils versions do not include symbol version information). This commit re-uses scripts/abilist.awk with a tweak to include GLIBC_PRIVATE symbols. This awk script is based on objdump -T output, which appears to be stable over time.
