Ok, so it doesn't fail when building the rootfs, but when building
U-Boot.

This is known issue with old versions of U-Boot.

You can try adding
board/roseapplepi/patches/uboot/0001-compiler-.h-sync-include-linux-compiler-.h-with-Linu.patch
as a U-Boot patch, or preferably update your U-Boot to a more recent
version.
