Can't build binutils on OpenSuSE or Ubuntu

[Moran, Chris]

I am following the build instructions at:
http://www.rtems.org/onlinedocs/releases/rtemsdocs-4.10.2/share/rtems/html/s
tarted/started00034.html

I found that the patches listed in this document didn’t exist on the ftp
server, so I am using binutils-2.20.1 and
binutils-2.20.1-rtems4.10-20130320.diff

The patch applied without error

The command give to configure was "../binutils-2.20.1/configure
--target=i386-rtems --prefix=/opt/rtems" which ran without error

When I run make, the compile halts with the following error:

make[4]: Entering directory `/opt/rtems/tools/b-binutils/bfd'

I get the same error on a clean install of either OpenSUSE 12.3 or Ubuntu
13.04.  Any suggestions what I may be doing wrong?
