BUG: Fix Xcode linker language

Xcode does not seem to support direct requests for using the linker for
a particular language.  It always infers the linker using the languages
in the source files.  When no user source files compile with target's
linker language we add one to help Xcode pick the linker.

A typical use case is when a C executable links to a C++ archive.  The
executable has no C++ source files but we need to use the C++ linker.
