AppImage requires recent glibc

[ath3]

I am happy to see there is now an appimage for clifm. Unfortunately it requires a recent version of glibc.

This section of appimage concepts decribes well what i would like: https://docs.appimage.org/introduction/concepts.html#build-on-old-systems-run-on-newer-systems

Thanks in advance!
