To be honest, I do not understand what you are trying to do here.

This file should be built and installed on 386-pc platform. If not
either there is a bug, or you are doing something wrong. It is hard to
tell, you are doing so many steps ...

Just built and install grub for each platform you want to use;
grub-mkrescue will automatically include every platform it finds.

It is better to explicitly force host platform with --host=.... to make
sure user space is always the same. Otherwise it should be fine.

I prefer to build every platform in separate directory, there were
issues with incomplete cleanup. If you hit one, please report.

There are no configuration files after "make install" (if we do not
count /etc/grub.d as configuration).
