From 72c29925637ee51c505d9d12e22564573ab83e29 Mon Sep 17 00:00:00 2001 From: Anisse Astier Date: Fri, 11 May 2018 22:50:34 +0200 Subject: [PATCH] go: cleanup cross-compilation support Now that we fixed cross-compilation in the go package, cleanup the build to remove the workaround added in 60c5c96ae109dcea48e0997b5e6e6645ac9b86 "package/go: Build host tools with host CC". We only need a single pass to build the go toolchain.
