I believe this is only necessary if a port makes use of fr_var in
machine-dependent code.  The generic code doesn't care about fr_var in
rs_machine_dependent frags.

No, we don't want to do that.  x86 uses fr_var to hold a reloc type.

Thanks again for cleaning up after me.  I suspect that if fr_var was set
correctly first time around, you wouldn't need to do anything on
subsequent relax passes.
