Christian Stewart 8a1158f89f package/go: add support for riscv64 architecture
Enable the supported "riscv64" GOARCH.

Add a patch to fix a build failure due to GOARCH leaking into the calls to the
go-bootstrap compiler. Unsets the GOARCH before calling go-bootstrap.

Subject: [PATCH] build: bootstrap: set environment before generating buildcfg
The GOOS and GOARCH environment variables should be unset before calling
mkbuildcfg. This change fixes a build failure when GOARCH=riscv64.
Building Go toolchain1 using go-1.4-bootstrap-20171003.
src/cmd/compile/internal/ssa/rewriteRISCV64.go:4814
invalid operation: y << x (shift count type int64, must be unsigned integer)
There is a build issue with go1.4 with the riscv64 code: however, why is the
riscv64 code being compiled at all?
GOARCH is set when calling mkbuildcfg, so go1.4 is trying to compile riscv64.
