It turns out that Go 1.4.3's cgo (the Go interface to C code) doesn't work with Binutils > 2.27: https://github.com/golang/go/issues/16906 We are still able to use Go 1.4.3 to bootstrap later versions of Go if we disable cgo, as I did in 04a95a4fd66.

Try fixing the version of the toolchain to something older, perhaps? Andy
