Comment (by Ionic):

 I've implemented overrides via the Darwin major version now anyway.

 Also fixed up the stuff for thin object files, fixed a few mistakes and
 split `best_fchdir` out into its own compilation unit so that it will only
 be generated once (since we really only need it once anyway), saving
 space.

 I think I'm about happy with that implementation now.

 On 10.9 directly, `+universal`:

 {{{
 %  nm -arch i386 $(port work legacy-
 support)/destroot/opt/local/lib/libMacportsLegacySupport.dylib | grep
 fdopendir
 00002ac1 T _fdopendir

 }}}

 Faking 10.4, `+universal`:

 {{{

 I naturally am not able to test anything `ppc`-related, but I believe
 it'll likewise work.

 Does this look sane? Especially what is being faked for `i386` on 10.4?
