Subject: [PATCH] Add -ObjC link flag to fix OSX crashes

Add `-ObjC` link flag when building on OSX. As noted in
https://github.com/SFML/SFML/issues/2920, this is required when
statically linking against SFML since it contains Objective-C source
files. Without this flag, compiling and linking succeeds but binaries
will crash at runtime.
