This is required in some cases - e.g. compiling node.js for ARM64/Alpine, and the ever-broken ARM64 runtime perf lane (where we need headers for ARM64 available alongside linkable libraries for AMD64, depending on the build phase). As is, we've achieved the same result largely by accident in the pre-Mariner build images, where we have enough x64 in the host OS to link successfully, and the ARM64 files in the crossroot. The precedent on this is dotnet#901 which fixed our Android cross-compiler builds, by offering both Android and $HOST in the same system If at some point in the future we move from building on x64 to building on ARM64, we will need the equivalent images for that.

I've validated these images locally in dotnet/node#36 - I was able to cross-compile for Musl for the first time, and arm64 Ubuntu on Mariner without gross accidental functioning via the old Ubuntu images. |

There was a problem hiding this comment.
is the amd64-amd64 a typo? Or does it mean cross compiling from amd64 to amd64?

No. amd64 primary crossrootfs, amd64-alpine secondary
