Drop executable symbol export if platform does not support shared libs 

Instead of always adding CMAKE_SHARED_LIBRARY_LINK_<LANG>_FLAGS to
executables, or just when the ENABLE_EXPORTS property is set (CMP0065),
make sure that the target platform also actually supports shared
libraries.  If not, then the executable cannot possibly provide symbols
to them anyway.
