Does this change fix the problem described here?

About elf64-ia64-freebsd, I'm not sure it is needed. FreeBSD 4.0 and
older used non-standard ELF branding and that format got the name
elf32-i386-freebsd (and elf64-alpha-freebsd). Later versions of FreeBSD
use the standard method, but keep calling it elf32-i386-freebsd. Rather
than copying this practise to other architectures, maybe binutils should
be fixed for i386. It isn't used on amd64 and sparc64 either as far as I
can tell.
