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.
