| Subject: [PATCH] use GOBUILDMODE to set buildmode |
| |
| While building go itself, the go build system does not support |
| to set `-buildmode=pie' from environment. |
| |
| Add GOBUILDMODE to support it which make PIE executables the default |
| build mode, as PIE executables are required as of Yocto |
| |
| Refers: https://groups.google.com/forum/#!topic/golang-dev/gRCe5URKewI |
| Upstream-Status: Denied [upstream choose antoher solution: `17a256b |
| cmd/go: -buildmode=pie for android/arm'] |
