Test OBJECT library use without other sources

Reference OBJECT libraries for inclusion in targets that have no other
sources to verify that the linker language propagates correctly from the
object libraries.  Test with a STATIC library, a SHARED library, and an
EXECUTABLE target.  Use the static and shared libraries each in
executables that end up using the object library symbols.

In VS 6, 7, and 7.1 add a dummy object file to convince the IDE to build
the targets without sources.  In Xcode add a dummy source file to
convince it to build targets without sources.
