  To: libc-alpha; +Cc: bergner, Amrita H S

The following three changes have been added to provide
initial Power11 support.
    1. Add the directories to hold Power11 files.
    2. Add support to select Power11 libraries based on AT_PLATFORM.
    3. Let submachine=power11 be set automatically.

Peter, are you going to approve/merge this?
