Reproducing If possible, provide a list of commands or a code sample that
reproduces the bug that you are observing. Otherwise please describe as much as
possible in which circumstances the bug can be observed.

A yarn workspaces focus of a project with zeromq == "^6.1.2" on arm64/armhf will produce a node.addon for x8664, ignoring npm_config_arch.

Patching package.json to include the additional configuration for arm64/armhf does not change this situation.

Expected behavior A clear and concise description of what you expected to
happen.

The correct addon architecture is produced for the target system.

Tested on
