Implement -rdynamic

Currently ghc ignores the -rdynamic flag.

With a small effort it can be used as a synonym of -optl -rdynamic in linux and -optl -export-all-symbols in windows/mingw32.

In other platforms, similar translations must be possible to get the symbols of an executable exported.

This feature would improve usability of an upcoming implementation of #7015 (closed).
