-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>.
