As I was unable to update the skype on linux properly (no x32 arch package) and the forced incompatibility is just a **** move, I can recommend this "solution" to make skype a "higher" version:
sudo sed -i 's/4\.3\.0\.37/8\.3\.0\.37/' /usr/bin/skype
It replaces the version number in the binary for a higher one to work around the forced incompatibility.
Make sure that you have the same version 4.3.0.37 by calling skype --version or update the command accordingly.
