It support dynamic compilation,and remove the todo. And there's no problem in cross compilation.
It just support compile now.

You need to add a Signed-off-by: line to your commit(s) which indicates that you attest the Developer Certificate of Origin a statement about your contributions that you must read before signing (don't worry, it's quite short and easy-to-read). You can add it to your commits with git commit --amend -s, and then doing a git push --force.

NOTE: This is a saved reply. Sorry if it reads as a cookie-cutter response, it was written so that newcomers understand what a "DCO" is and make the process for contributing a little less scary.

Sorry for noticing that pr , but this draft seems to have not been updated for a long time. I will close this first ,and wait for that pr update.If CI wants to support cross compilation, it seems that there is still some work to be done.
