Please reply on the list...

No, the rdynamic flag is not in the CMAKE_CXX_FLAGS.   It comes from here:

macro(__linux_compiler_gnu lang)
   # We pass this for historical reasons.  Projects may have
   # executables that use dlopen but do not set ENABLE_EXPORTS.
   set(CMAKE_SHARED_LIBRARY_LINK_${lang}_FLAGS "-rdynamic")

You should be able to put that in your toolchain file if you are doing 
cross compiling.  You are getting the generic linux config.
