[RFA] Fix compilation failure in bfd/som.c under HPUX 11.00

[Joel Brobecker <brobecker at act-europe dot fr>]

There is a small error in this file. The type of the parameter current_offset in function som_write_symbol_strings () do not oatc  between the declaration of the function (declared as unsigned long)
and its implementation (declared as file_ptr). Judjing from the rest of
the code, it should be "unsigned long".

So I suggest the following change. With the changes to hpux-thread.c
reported earlier, this is the only other change that I needed in order
to compile GDB on HPUX-11.00. For the same reasons, I did not have time
to test it, it also seems quite reasonable a change.

        * som.c (som_write_symbol_strings): Fix incorrect type of
        current_offset to match the function definition. Fixes a build
        failure on HPUX-11.00
