It isn't.  It's in <linux/elfcore.h>; I forget the exact path
by which this gets pulled in.  This is fairly losing, and just
the way it's "always been done".

You'll be modifying elf_backend_data in bfd/elf-bfd.h, and elfxx-target.h
to make what is currently elfcore_grok_prstatus switched on the target.

You'll copy that function to elf64-alpha.c and tweek it to handle two
different prstatus_t layouts.
