The host-grub2 modules build can be fixed by the following patch:

--- a/boot/grub2/grub2.mk
+++ b/boot/grub2/grub2.mk
@@ -125,7 +125,9 @@ GRUB2_TUPLES-$(BR2_TARGET_GRUB2_ARM64_EFI) += arm64-efi
 # use the cross compile variant to ensure grub2 builds

 HOST_GRUB2_CONF_ENV = \
-       CPP="$(HOSTCC) -E"
+       CPP="$(HOSTCC) -E" \
+       CFLAGS="$(HOST_CFLAGS) -Os" \
+       CPPFLAGS="$(HOST_CPPFLAGS) -Os"

 GRUB2_CONF_ENV = \
        CPP="$(TARGET_CC) -E" \

Regards,
Peter
