Wasn't there something similar with rtld recently? The problem with the rtld was that it made assumptions about the order of the elf sections in ld-elf.so. Here's what Peter said in his commit message: ld-elf.so.1 assumed a few too many things about the ordering of sections produced by ld(8) (ie: that _DYNAMIC immediately follows the _GOT). The new binutils import changed that, and the intial GOT relocation broke. Use a custom linker script to provide a real end-of-GOT symbol.
