[PATCH][GOLD] Fix ARM kernel build problem due to stub sizing.

[Doug Kwan (關振德)]

Hi Ian,

    This fixes a problem in which an assert is triggered because
current data size is not up to date.  I can the code to compute the
accurate value instead in Arm_input_section::set_final_data_size.
Becuase we have 3 stub types and hence 3 sub-tables in a stub table,
tracking the size accurately is not very efficient.

        * arm.cc (Arm_input_section::set_final_data_size): Compute
        accurate final data size instead of using current data size.
