Auto merge of #139242 - jieyouxu:run-make-artifact-names-cross, r=<try>

[WIP] run-make-support: Calculate artifact names for target platform, not host platform

This was implemented incorrectly during the porting process, where we relied on std consts. However, `run-make-support` is a host-only library, which meant that these artifact names were for the *host* and not the *target*.

Helps with #138066.
