Due to some historic cruft this compiler is not supported on Linux right now.
In "Modules/Platform/Linux.cmake" comment out the line

  SET(CMAKE_SHARED_LIBRARY_LINK_C_FLAGS "-rdynamic")

This is on our TODO list for 2.8.x but we didn't want to mess with the
widely used Linux.cmake platform file just before the 2.8.0 release.
