The following patch updates the following directories to use the latest 
versions of libtool, autoconf, and automake:

bfd binutils gas gdb gprof ld libiberty mmalloc opcodes rda sim utils

ltmain.sh (GNU libtool) 1.4.3
autoconf (GNU Autoconf) 2.56
automake (GNU automake) 1.7.1
gettext (GNU gettext) 0.11.5

To apply the patch, I put the following four files in a directory, and 
ran 'files.sh' in the top-level directory of the GDB/Binutils tree, 
then configured and built with 'build.sh' (the script was necessary in 
order to pass --enable-maintainer-mode to only the subdirectories for 
which it was appropriate).  I then did a full build to verify that 
maintainer-mode was working, and used the files generated by 
--enable-maintainer-mode as the final versions.  I'm not including the 
ChangeLog entries for all of the auto-generated files, as they're not 
overly interesting; I plan to generate them with a perl script based on 
the result of the build.  I'm also not including the diffs to the 
generated files, since they were about 6Mb, and not all that 
interesting.  I'm happy to provide either if requested.
