Bug#1070059: p11-kit FTBFS with gcc-14 due to -Wincompatible-pointer-types having become an error

p11-kit fails to build from source when built with gcc-14. In gcc-14,
-Wincompatible-pointer-types has become an error. For instance, the
armel build currently says:

This will become a hard failure once we swicth to gcc-14.
