Oh silly me.  I forgot that we default to prefix=/usr/local, and
then we end up not picking the /usr/debug debug dir by default.
Building with --prefix=/usr made catchpoints now work.  And I had
stumbled on this before when I hacked on Ada catchpoints a
while back, and just forgot about it.  The good
news is that I still get all passes, sync and async.  :-)

Now I don't know if I needed any extra package compared to what
I had already installed, or if I did, which . :-P  In any case, it's
clear the necessary symbols aren't in any library's minimal symbols.
