objc failures on branch

[Nicola Pero]

> For i686-linux I get the following failures on the branch:

I don't know why bf-* and paste are failing on your machine - I've never
seen them failing in my tests - this is what I get on the branch on my
machine -

Native configuration is i686-pc-linux-gnu

<nested-1.m is not included but unfortunately I know it is failing as
well on the branch.>

Zack's patches fix np-1.m, np-2.m, bycopy-1.m and bycopy-2.m - not the
bf-* and paste <which I thought would already work>.

Since *all* your objc tests are failing in the branch, there might be some
other basic problem with objc ?  <such as not finding -lobjc or not
finding objc system include files or not finding the thread library or
something of this kind>
