It should be fixed in the Linux binutils 2.15.90.0.2:

Changes from binutils 2.15.90.0.1.1:

1. Update from binutils 2004 0412.
2. Add --as-needed/--no-as-needed to linker.
3. Fix -z defs in linker.
4. Always reserve the memory for ia64 dynamic linker.
5. Fix a race condition in ia64 lazy binding.

The current one is 2.15.91.0.1.
