cf4aca11b5 In the `I can't believe it's been broken all this time' department: 
_rtld_bind_start must save and restore the condition codes.  Varargs functions
(like, say, printf()) depend on the state of cr1 to determine whether they need
to store floating point registers in the save area.  Without this, the first
call to any particular varargs function will fail if floating point values were
passed.

7ff3aa31e8 Reorganize PowerPC cold a little. The return value from _rtld_bind_pltgot() 
was ambiguous in the case of a weak symbol that was not defined.  This caused
RTLD_NOW to fail badly with shared libraries linked against the new crtbegin.o.

* Apply DT_PLTRELSZ to (one of) pltrel or pltrela *after* we've finished
  parsing the headers, so we know which one.

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.

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.

f00af7b07c Oops - when assembled with PIC, the jal gets expanded, so what used to be 
in the branch delay slot was no longer getting executed at the proper time.
This resulted in a corrupt ps_strings pointer and caused programs trying to
use ps_strings to fail.

41fe218b25 First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf 
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.).  This runs, but it's
in serious need of cleaning and/or a fair bit of reworking.  See the README
file for more information, and a list of things to do.
