Add cmake configuration to select if stubs include symbols 

G++ generates structure debug symbols for a few df namespace classes to
generated stub source files. I decided to test how much symbols from
those files would increase binary size. When the result was about double
size I decided to add cmake configuration option to let user easily
select if they prefer complete symbols or reduced size.
