* fix for Mantis #36706: only link a library against the dynamic loader if we're not linking against the C library anyway

Note: I did not yet find a case where we *do* need to link a library against the loader; this will have to be investigated further, but for 3.2.0 this is safest
........
* fix for Mantis #36738: when copying a record using its copy operator we assume that we've copied the whole record; this way managed records inside non-managed records are handled correctly
+ added (adjusted) test
........
* when checking for an existing operator overload for the assignment operator, check for the correct variant (explicit or not) matching the overload
+ added tests
........
* GetLoadErrorStr (currently) returns a ShortString, so avoid a useless conversion to AnsiString
