C++ Exceptions - Custom Link cmd required?

When enabling C++ exceptions in a project the following linker warning appears:

warning #10247-D: creating output section ".c6xabi.exidx" without a SECTIONS specification
warning #10247-D: creating output section ".c6xabi.extab" without a SECTIONS specification

Now, the first thing I try (since RTSC based projects normally don't need a custom linker command file) is to add the following to my .cfg:

Program.sectMap[".c6xabi.exidx"] = "DDR3";
Program.sectMap[".c6xabi.extab"] = "DDR3";

This results in an warning and the lines are ignored:

"./configPkg/linker.cmd", line 218: warning #10094-D: split placement (>>)
   ignored for ".c6xabi.exidx":  cannot split EH Index table

..and so I am forced to create a custom linker command file to link correctly.

Is there a way to solve this problem in the .cfg, without having to resort to creating a custom linker command file?

Thanks,
