[CMake] ctest coverage and gcc 3.4

[Wheeler, Frederick W (GE, Research)]

As of version 3.4, gcc has changed the format of the coverage files you get with options -fprofile-arcs -ftest-coverage.  Also, the coverage files now have suffixes .gcno and .gcda.  On a ctest build/test/submit run with coverage, ctest prints "Cannot find any coverage information files (.da)".  There are plenty of .gcno and .gcda files in the build tree, but it does not seem to be looking for them.  Is there a solution?

This changes file briefly notes the coverage file format change.
