[parisc-linux] Fix for hppa-linux ld.so with newer binutils

[Carlos O'Donell Jr.]

I was beggining to wonder...

  /* Figure out the run-time load address of the dynamic linker itself.  */
  bootstrap_map.l_addr = elf_machine_load_address ();

  /* Read our own dynamic section and fill in the info array.  */
  bootstrap_map.l_ld = (void *) bootstrap_map.l_addr + elf_machine_dynamic ();
  elf_get_dynamic_info (&bootstrap_map);

_dl_start (0x41002b74).... 
_dl_start+312 (Assertion failure with wrong address for initialized data) 

Why aren't .got entries being initialised?

So you are saying we need to make all of our global symbols constant
so that we can access them during the bootstrap? (No more _DYNMAIC?)

And that elf_machine_load_address is trying to access symbols that aren't
setup yet, because ELF_DYNAMIC_RELOCATE() hasn't been run yet?
And thus hasn't setup any of our offsets... where has my pic code gone ;(
