Comment (by Ionic):

 I finally have a working go 1.12.1 build on OS X 10.9

 It's horrid, but it bootstrapped itself successfully. It likely won't work
 out of the box for users (i.e., in the case users want actually use go on
 their go source code), but there isn't anything I can do about that, I
 guess.

 Users will have to disable the internal linker/force the internal linker
 and at the very least pass the **external** `LDFLAGS` `-L${prefix}
 -lMacportsLegacySupport` for binaries to work, I guess, if they are using
 any features provided by `legacy-support` (even pulled in via the core).

 Is this acceptable?

 I'm going to polish up the `Portfile` tomorrow and submit a PR to `legacy-
 support` for `fstatat64` support. Without that, it won't work, so we'd
 probably need a `legacy-support` release/RC with that new `fstatat64`
 support in before the `go` port can be fixed.
