    libobjc: Add cast to void* to disable warning for casting between 
incompatible function types [PR89586]
    
    Even though __objc_get_forward_imp returns an IMP type, it will be casted 
to a compatable function
    type before calling it. So we adding a cast to `void*` will disable warning 
about the incompatible type.
    
    Pushed after bootstrap/test on x86_64.

            * sendmsg.c (__objc_get_forward_imp): Add cast to `void*` before 
casting to IMP.
