    libiberty, Darwin: Fix a build warning.
    
    r12-3005-g220c410162ebece4f missed a cast for the set_32 call.
    Fixed thus.

    libiberty/ChangeLog:
    
            * simple-object-mach-o.c (simple_object_mach_o_write_segment):
            Cast the first argument to set_32 as needed.
    
    (cherry picked from commit 38757aa88735ab2e511bc428e2407a5a5e9fa0be)
