LGTM

I like the idea which decoupling the parsing logic of the normal march string parsing, and we can have a simple parser logic here since ELF attribute has specified that should have explicitly version number and separated by `_`.

This also enable us could implement further complicated merge rule like merging unknown extension, different extension version and unsupported extension version - not just limited to handle knowing extension and supported version.
