;; According to https://golang.org/doc/install/gccgo, gccgo-4.8.2 includes a
;; complete go-1.1.2 implementation, gccgo-4.9 includes a complete go-1.2
;; implementation, and gccgo-5 a complete implementation of go-1.4.  Ultimately
;; we hope to build go-1.5+ with a bootstrap process using gccgo-5.  As of
;; go-1.5, go cannot be bootstrapped without go-1.4, so we need to use go-1.4 or
;; gccgo-5.  Mips is not officially supported, but it should work if it is
;; bootstrapped.
