 I updated and was able to successfully run BSDi 2 binaries directly now
 on HEAD (9.99.69) on amd64.  Really great to see this happen, thank you!
 
 I found that after updating to HEAD on i386 the BSDi 2 binaries and
 other previously working early NetBSD a.out binaries now failed although
 they all ran on amd64.
 
 I've sent you further details off list, but a sample for NetBSD 1.0 is
 below and please feel free to tell me if I need to file a new PR.
