commit 84df08debf13562f8a1fc7cd59054aaa9c379294

    Enable Opt_PIC for the dyn way regardless of OSes.
    
    We were previously enabling Opt_PIC on certain OSes namely Windows,
    Darwin and Linux, but it should always be enabled for the dyn way
    because it makes no sense to try to generate non-PIC dynamic
    libraries, which is usually impossible.
