As far as I can understand, it's not possible to build gcc 4.0.0 and gcc 3.4.* using GNU binutils with current release 2.15 of GNU binutils. One has to use the CVS sources or at least one file.
FYI binutils-2.16 has just been released. You might want to try that.
Not clear if there will be a binutils-2.15.1 release, but if you check out the binutils-2_15-release tree from sourceware.org cvs, then it includes the patch that you need. It was added to the release branch after the binutils 2.15 release was made.
Bug ID: 4910101
Synopsis: fbe needs a way to reference section labels
Category: compiler
Subcategory: assembler-x86
Apparently this problem only shows up for x86 when using Sun tools, but when using GNU tools, it also shows up for sparc.
