Okay. That's good to know. What I can do to make it a little nicer is to
just put the bare minimum into elf.c and then split our other support
functions out into separate file that will only be compiled for our target.
Second question. The header file that it requires (nto_debug.h) used to be
in the top level include directory but it seemed to me that any nto specific
includes should be in an 'nto-share' directory in the gdb heirarchy.
Unfortunately, binutils doesn't rely on gdb being present so I'm thinking
that it might need to be in the 'include' dir. Is there some other way to
do this? It doesn't look like the include dir is overly cluttered and I
might find some resistance since there aren't really any target specific
headers there. Perhaps if I just take the definitions I need and put them
into the nto specific file I mentioned earlier?
