Remove dependency of all-target-libobjc on maybe-all-target-libiberty

Remove dependency of all-target-libobjc on maybe-all-target-libiberty

[Nicola Pero]

This patch removes the (maybe) dependency of libobjc from target libiberty from
the makefiles.

I don't know of any reasons why libobjc would need target libiberty; I also looked around
and couldn't spot anything.  Most other target libraries don't depend on libiberty; I'm
not sure why libobjc would need to.  I think the dependency is bogus, probably exists
for historical reasons and the fact that nobody reviewed that piece of code for a long
time, and should go away. :-)

It wouldn't matter much, but I saw that some people are keen to remove the target libiberty
completely, and I wouldn't want them to spend time trying to figure out why libobjc needs
it.  It doesn't. ;-)

Ok to commit ?

Thanks
