when we are doing immediate binding, leave them alone and they will be dealt
with later during lazy binding. From skrll@

38bdc8954f Refactor common code to _rtld_relocate_plt_object to i386 and arm so they 
act like the other versions.
In _rtld_bind, if the result is 0, call _rtld_die.
Initialize _rtld_sym_zero.st_value to -_rtld_objself.maprelocbase.  Now when
the symbol is resolved, st_value + maprelocbase will equal 0 and the above
check in _rtld_bind will fire and a call to NULL will be avoided.

using the ${LDFLAGS:@F@-Wl,$F@} make substitution because that breaks

eea1001a73 Adjust for the fact that the GOT is all 0s in new binutils -- do the trick of 
disassembling a call to _DYNAMIC to determine its real address, and using the
first entry of the GOT as its base-relative address.

It's evil, but it works.

d4e6f3ff08 Swap registers %o0 and %o1 in the binder stub to say one instruction. 
Fix an obvious bug in the 64-bit PLT fixup: the SLLX was by 12 bits, when it
should be 32.

Fix what *appear* to be two bugs in the >32768 PLT entry stub:
* One division was wrong (/14 rather than /24).
* We need to subtract 1048576 (to make the offset relative to the beginning of
  the upper section), not add it.
This path is still untested, and buggy.

6f0fac5efa Pass down an additional flag to _rtld_relocate_nonplt_objects() which 
indicates whether we're relocating ld.elf_so itself.  Use this in some places
rather than hackish tests on `dodebug'.  (The Alpha and HPPA `dodebug' tests
were actually noops, because RTLD_RELOCATE_SELF is not set, and therefore
dodebug is always true.)

a04012e731 Split _rtld_relocate_plt_object() into two MD functions: 
* _rtld_relocate_plt_lazy() fixes up all the relocs pointing to the PLT.  (On
  most platforms it just does a simple base-relative fixup; on SPARC it does
  nothing.)
* _rtld_relocate_plt_object() does immediate binding for a PLT entry.
The basic gist is that this saves a bit of time on SPARC (where the iteration
through the pltrela table was gratuitous), and a little less time on all other
platforms.  A whole lot of #ifdef'ed crap is moved out of reloc.c, too.

NOT tested on: hppa sh x86_64
