I think I'm seeing the same thing (or at least something related) on 
macppc - after the "preserve l_private across forks" change, the number 
of test failures jumped from 11 to 243 (see 
http://www.netbsd.org/~riz/macppc-atf/ ) .  As in Frank's case, the 
ppc-tls-diff.txt change does not actually fix it.
