This 2-patch series posted to grub-devel by Alex Tuesday evening
resolves this issue:
https://lists.gnu.org/archive/html/grub-devel/2019-04/msg00130.html

1/2 also satisfactorily explains why there was a difference in
behaviour between images generated by grub-mkimage and
grub-mkstandalone (trampolines spilling over into different sections).

>From code review as well as some (but not exhaustive) testing, this
seems like a no-op for all !armhf platforms.

Could these two patches be cherry-picked into Buster please?
