This seems like a potential bug.  Suppose some aspect of libgcj
configuration depends on the multilib?  Offhand I can't think of when
it would happen, though, so I guess we can continue to ignore it.
Certainly it doesn't happen now.

I assume multilib installs are serialized.

Thanks for digging into this.  This is one of those odd bits we hope
will go away when specs are removed.
