Thanks, much appreciated.

I wonder what's that 'the latest additions to mips.lds and u-boot.lds
for supporting recent binutils' to be exact.  Which commit(s) are you
referring to? Or could you provide error logs just in case please?

Hmm.  According to the README file, even the Linux kernel still builds
with at least gcc 3.2.  I'm feeling that it might be a bit too early to
drop gcc 3.3.3 (ELDK-3.1.1).

So I'd like to take a look at the issue you found this time, first.  If
it's easy to fix, let's fix it.  And if not, revise the patch please.
We have not heard of any problem reports on MIPS builds with ELDK-3.1.1
so far (at least I'm not aware of them).  The change won't be a problem.
