A powerpc patch from Ronald Wahl:

    Ok, now i got it after a day of work.

    I have had a look into glibc and found the following:

    sysdeps/powerpc/dl-machine.c:
    ...
	case R_PPC_JMP_SLOT:
	  /* It used to be that elf_machine_fixup_plt was used here,
	     but that doesn't work when ld.so relocates itself
	     for the second time.  On the bright side, there's
	     no need to worry about thread-safety here.  */
	  {
	    Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr;
    ...

    The comment made me suspicious. The same position in uClibc looks like this:

    ldso/ldso/powerpc/elfinterp.c:
    ...
	    case R_PPC_JMP_SLOT:
		{
		unsigned long targ_addr = (unsigned long)_dl_linux_resolve;
		int delta = targ_addr - (unsigned long)reloc_addr;
    ...

    When I change it to the following it works:
    ...
	    case R_PPC_JMP_SLOT:
		{
		unsigned long targ_addr = *reloc_addr;
		int delta = targ_addr - (unsigned long)reloc_addr;
    ...

    I hope it will not break anything. Can anyone review this change and
    commit it into CVS?

    thanks,
    ron
