cmd/dist: skip building std for the host when cross-compiling
The purpose of building the host toolchain is so that we can use it to
build and test the target configuration.
The host configuration should already be tested separately (with its
own builder), so we do not need to build the parts of that
configuration that are not relevant to the task of building and
testing the target configuration.
Updates #47257.
