Subject: [PATCH 8/9] cmd/go: Use GOBUILDMODE to set buildmode

Upstream-Status: Denied [upstream choose antoher solution: `17a256b
cmd/go: -buildmode=pie for android/arm']

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
