* elf/dl-fini.c (_dl_fini): Increment j counter after swapping in
element at this position.
* elf/Versions [ld.so] (GLIBC_2.2): Export _dl_load_lock.
* elf/link.h (struct link_map): Add l_reldepsmax, l_reldepsact, and
l_reldeps elements.
* elf/dl-lookup.c (add_dependency): New function.
(_dl_lookup_symbol): Use it whenever symbol was found in a global,
dynamically loaded object.
(_dl_lookup_symbol_skip): Likewise.
(_dl_lookup_versioned_symbol): Likewise.
(_dl_lookup_versioned_symbol_skip): Likewise.
* elf/dl-open.c: Don't define _dl_load_lock here...
* elf/rtld.c: ...but here...
* elf/dl-support.c: ...and here.
* elf/dl-close.c (_dl_close): Close also dependent objects introduce
through relocation.
* elf/dl-fini.c (_dl_fini): Also take dependencies introduced through
relocations.
* dlfcn/Makefile (glrefmain.out): Test is not expected to fail
anymore.
* dlfcn/glrefmain.c: Add one more debug message.
* Makeconfig (preprocess-versions): Don't add $(CPPFLAGS) to compiler
command line.
* Makerules (sysd-versions): Use ( ) instead of { }.
* elf/dl-load.c: Use __builtin_expect to signal that compiler should
optimize for the non-debugging case.
