This indeed happened to be also in building 2.4.27-nubus powerpc kernels, so i
guess you are on powerpc also, right ?

You probably have some kind of ld.script thingy somewhere, hopefully, if not
you need to create a new one. This one has a .sdata entry, and you need to put
a _SDA_BASE_ tag before it, like :

      _SDA_BASE_ = .;
           *(.sdata)

not sure how to do it if you don't have a separate ldscript though, and you
probably need to write a ld.script yourself to solve it.

Now, this may also be a bug in binutils, which is currently some somewhat
problematic CVS snapshot, so you may want to file a bug report against it.
