* core.c (core_sym_class): Ignore symbols without BSF_FUNCTION

Browse source 
set if ignore_non_function is set.
        * gprof.h (ignore_non_functions): Declare.
        * gprof.c (ignore_non_functions): Define.
        (long_options): Add "ignore-non-functions".
        (usage): Add new options.
        (main): Recognize "-D" and "--ignore-non-functions" option.
So we can get more accurate information on Solaris, HPUX and other
systems that can uniquely identify function symbols.

@c This is compatible with Unix @code{gprof}, but a bad idea.
This option affects both the flat profile and the call graph.
@item -D
The @samp{-D} option causes @code{gprof} to ignore symbols which
are not known to be functions. This option will give more accurate
profile data on systems where it is supported (Solaris and HPUX for
example).
@item -e @var{function_name}
The @samp{-e @var{function}} option tells @code{gprof} to not print
information about the function @var{function_name} (and its
