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. Update ld.so to deal with the new (faster) PLT format that gcc-3.1 and binutils can produce. This is probably incomplete, but appears to be working again. Obtained from: NetBSD (And a fix to a silly mistake that I made by: gallatin)
