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

Adapted to Go 1.13 from patches originally submitted to
the meta/recipes-devtools/go tree by
