[dcl.link] p10 objects vs. entities

[xmh0511]

[dcl.link] p10 says:

Linkage from C++ to objects defined in other languages and to objects defined in C++ from other languages is implementation-defined and language-dependent.
Only where the object layout strategies of two language implementations are similar enough can such linkage be achieved.

The objects should be changed to entities, which includes both objects and functions for which the linkage is applied.

Linkage from C++ to entities defined in other languages and to entities defined in C++ from other languages is implementation-defined and language-dependent.

It is the commit message that we'd like to see updated, not the PR title. (The PR title is not terribly important.)
