+Subject: [PATCH 7/9] cmd/go: make GOROOT precious by default
+
+Upstream-Status: Inappropriate [OE specific]
+
+The go build tool normally rebuilds whatever it detects is
+stale.  This can be a problem when GOROOT is intended to
+be read-only and the go runtime has been built as a shared
+library, since we don't want every application to be rebuilding
+the shared runtime - particularly in cross-build/packaging
+setups, since that would lead to 'abi mismatch' runtime errors.
+
+This patch prevents the install and linkshared actions from
+installing to GOROOT unless overridden with the GOROOT_OVERRIDE
+environment variable.
+
+Adapted to Go 1.13 from patches originally submitted to
+the meta/recipes-devtools/go tree by
+Matt Madison <matt@madison.systems>.
