(ld) bfd_abs_section in .rodata, but modified

[Petr Ledvina]

I just encoutered bug in ld for h8300:
GNU ld 2.11.2
  Supported emulations:
   h8300
   h8300h
   h8300s
compiled using gcc 2.95.4.

When I try to link against some absolute file(h8300-coff) using
--just-symbols=<absolute file>, ld crashes with segfault.

It seems that  bfd_abs_section is defined const (and gcc puts it in
.rodata), but coff_count_linenumbers tries to modify it.

Backtrace:
#0  0x8077353 in coff_count_linenumbers (abfd=0x80b6af0)

Source (in cofgen.c):
            {
              /* This symbol has line numbers.  Increment the owning
                 section's linenumber count.  */
              alent *l = q->lineno;

=>            ++q->symbol.section->output_section->lineno_count;
              ++total;
              ++l;
              while (l->line_number != 0)
                {
                  ++total;
                  ++q->symbol.section->output_section->lineno_count;
                  ++l;
                }
            }

q->symbol.section->output_section points to <bfd_abs_section>

Maybe I am doing somethig the wrong way, but at least some nice error
would be fine.
