Eclipse: fix #13358: don't create bad linked resources

directory where the project file is located (${CMAKE_BINARY_DIR}), which can
happen e.g. for EXECUTABLE_OUTPUT_PATH and related variables.

Now, it seems this code never worked.
If EXECUTABLE_OUTPUT_PATH was set to point into a subdir of CMAKE_BINARY_DIR,
the code did nothing.
If it pointed directly at CMAKE_BINARY_DIR or some other location, it created
a linked resource. I tested this with Eclipse Europa (3.3) and Juno (4.2), and in this
case both versions of Eclipse complained that this is a bad location for a linked resource.
