43cfeb27a9 Catch up with type changes. Also: 
* Apply DT_PLTRELSZ to (one of) pltrel or pltrela *after* we've finished
  parsing the headers, so we know which one.
* Fix sparc64 bogons.  (It works now!)

63465d3193 No need for RELOCATE_SELF since the VAX does real PIC. Rewrite the bind 
routine to deal with JMP .vs. CALLx differences.

3d5dc334de Don't try to get libc_pic from the libc compile directory. If we're doing a 
build, libc has already been installed.

741f18b695 Initial VAX ELF32 support (mostly untested). It's checked primarily for 
testing and archival for now.  I don't expect anyone to work with it
since the binutils and gas changes are still pending.  But you got to
crawl before you walk.

00e5621847 We need to compile with -DVARPSZ, because the sparc has a variable page 
size depending on arch. Make it an error to compile without it. This
caused -lposix linked programs to fail.

44672d5287 Simplify _rtld_start() a little, and shave some cycles. Spefically, there's 
no need to save the stack pointer.  Just push the space for the cleanup
and obj_main pointers before calling _rtld(), and pop it after loading those
pointers into the appropriate argument registers for the program entry point.

4e7849055a Add comment on the necessity of having to look at implicit memory addends

84cb65780e Cleanup global variable access so rtld can be self relocating. Also KNF 
reloc.c and move md sparc parts to arch/sparc/mdreloc.c
Now we don't need to load at address 0 on the i386 and the mips should be
trivial to fix.
