| 4 | Subject: [PATCH] use GOBUILDMODE to set buildmode |
| 5 | |
| 6 | While building go itself, the go build system does not support |
| 7 | to set `-buildmode=pie' from environment. |
| 8 | |
| 9 | Add GOBUILDMODE to support it which make PIE executables the default |
| 10 | build mode, as PIE executables are required as of Yocto |
| 11 | |
| 12 | Refers: https://groups.google.com/forum/#!topic/golang-dev/gRCe5URKewI |
| 13 | Upstream-Status: Denied [upstream choose antoher solution: `17a256b |
| 14 | cmd/go: -buildmode=pie for android/arm'] |
