Need to update libbfd.so on RH AS 2.1 / IA64

Description of problem:
The installed version of libbfd.so cannot handle some object files generated
by gcc 3.0. In particular, the function bfd_find_nearest_line will barf on
some objects with the following error message:
BFD: Dwarf Error: Invalid or unhandled FORM value: 14.
Unfortunately, the function will abort with this error message rather than
just return an error code, so there is no easy workaround.
If you look at bfd/dwarf2.c in binutils-2.11.2 there is in fact no handler for
DW_FORM_strp (14). This apparently has been fixed in binutils-2.13.2 so we
should probably update to that.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Compile C program with gcc 3.0.2 and -g
2. Write program to open object bfd and call bfd_find_nearest_line
3. Run program on previously generated object file
As a workaround, one answer might be to compile programs with -gstabs or
-gstabs+ as a workaround. That would probably bypass the Dwarf-2 issues.
gcc 3.x is not supported on AS 2.1
Only gcc 2.9x
There are several changes that would be needed in binutils and
even more so in gdb, I don't think the changes are appropriate for
AS2.1 at this point.
