I don't understand what the need is for this to be different from other
machines.  I guess _SDA_BASE_ is some magic symbol that needs to be
resolved in the executable.  But I can't see that libc uses this value,
so I am quite confused.

I don't see any need at all for it on PPC64, where _SDA_BASE_ is not used.
I think we should switch PPC64 to using the normal signature for

It doesn't change often, but all changes to it are subtle and usually
important.  I really am not happy with the duplication.  When I fully
understand what needs to be different on powerpc, I will clean it up.
The __aux_init_cache bit is easy to insert in a clean way.
I need to understand the rationale for the other differences.
