run findstatic.pl over gprof

[Ben Elliston <bje at au1 dot ibm dot com>]

I ran the very useful `findstatic.pl' script (written by Andrew Tridgell) over the
gprof directory.  It turned up a few candidate variables to be made static (and found
 some unused ones, too).  I'm committing the following as obvious.

I have quite a few more patches for the other binutils directories, but that will
need to wait until tomorrow. :-)

        * corefile.c (core_num_syms): Make static.
        (core_syms): Likewise.
        (min_insn_size): Likewise.
        * gprof.c (abfd): Remove unused variable.
        * hist.c (hist_dimension): Make static.
        (hist_dimension_abbrev): Likewise.
        * sym_ids.c (id_list): Likewise.
        (table_name): Likewise.
