To package a go application in Yocto, one needs to also package its
dependencies to keep the build reproducible and under control. The
default install task of the go class puts the source in ${libdir}/go/src.
${libdir}/go/src is where the standard go packages resides, aka $GOROOT.
When a go package has dependencies on other go packages, they must be
located under $GOPATH, otherwise errors like this one may happen:
Non-standard package <packagename> in standard package <packagename>
This point of this patch is to trigger a discussion on how this issue
can be tackled in Yocto. Following code is working but should not be
considered for inclusion.
