On the one hand it is odd; but on the other it can be argued for from a
black-box perspective.  The reason I skipped this for libiberty is that
gdb uses its own "install-only" target when entering subdirs; but this
is neither GNU nor generally used in the rest of the tree.  So, it
caused installation to fail.

It's possible to fix this another way, say entering libiberty and using
the "install" target there.  But it seems not worth the effort to me;
first because we don't want to install anything in libiberty (unless one
highly values the black box approach, which I do not); and second
because eventually I will be moving all this stuff to the top-level
anyway.
