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']
