I think it should be iip instead of rp:

 #define	_UC_MACHINE_PC(uc)	((uc)->uc_mcontext.mc_special.iip)

but it fine to leave for now if you don't want to bother.  We still need
__gregs, __fpregs, and a bunch of other things in that file anyway.

So building release with my local changes
  build.sh -V HAVE_GCC=53 -V HAVE_BINUTILS=226 -V HAVE_GDB=710 -U -m ia64 release
gets a lot farther, but I am now getting a link error for some floating
functions with these new tools (the old tools built fine):
