Subject: [PATCH 5/7] cmd/go: make GOROOT precious by default
|
|
|
|
For OE builds, we never want packages that have
|
|
already been installed into the build root to be
|
|
modified, so prevent the go build tool from checking
|
|
if they should be rebuilt.
|
|
|
|
Also add an environment variable to override this
|
|
behavior, just for building the Go runtime.
|
|
|
|
Upstream-Status: Pending
