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.

Large C++ programs such as are found in KDE are a prime example. While relocating a shared object, maintain a vector of symbols which have already been looked up, directly indexed by symbol number. Typically, symbols which are referenced by a relocation entry are referenced by many of them. This is the same optimization I made to the a.out dynamic linker in 1995 (rtld.c revision 1.30). Also, compare the first character of a sought-after symbol with its symbol table entry before calling strcmp(). On a PII/400 these changes reduce the start-up time of a typical KDE program from 833 msec (elapsed) to 370 msec.
