Yes.  The section will come out as .core.kernel in objdump.  Perhaps
it should be .hp.core.kernel.  I'll leave the naming decision to you
and/or the binutils maintainers.  But I think that's better than
having all those .proc0, .proc1, .proc2 sections that we have now.
And it makes it easier to pick the right one from GDB.
