Linux: Some dynamic casts to types defined in plugin libraries fail on linux

Description

This seems to be a problem with symbol resolution. On linux, when dlopen loads a library the symbols are not made globally available by default.

This seems to cause problems when trying to perform a dynamic cast to types defined in the loaded library if the library has not been linked in with the calling application.

(In [4107]) Added RTLD_GLOBAL flag to dlopen on POSIX so that when a library is loaded then all of the symbols defined there are available to the calling application. I was seeing problems with some dynamic casts relating to this. Re #1157
