The golang select package.
We support three different variants of the golang compiler,
precompiled, which is a repackage of the builds available from golang.org;
cgo, which is compiled from source by conda-forge with CGOENABLED=1;
nocgo, which is compiled from source by conda-forge with CGOENABLED=0.
In version 1 conda will prefer the go-nocgo version by default, followed
by go-cgo and then go-precompiled.
