Too old. And, with the configure line you indicated (i.e. not specifying a
special assembler and linker), it is going to be used. So, you need to use more
recent binutils. (2.13.1 was released almost 6 years ago.)

Are you talking about the use of
/usr2/local/src/gcc-4.3-20080204/gcc-linux/./gcc/as? I think it's a symbol link
to the system "as" (or a short script calling said system "as"). It's a bit
misleading, but it's due to the way the build system works to be relocatable.

But PR10877 just mentions the first time a newer binutils was required. After
that, once it we require binutils >= 2.13.1, we can use all the new features in
that version without keeping track of them (because we're then garanteed to
have it present, it's a build requirement).
