rk3399 u-boot docs - arm tf-a compilation failure

[andrew at internet-e-mail.com]

Building TF-A (per https://docs.u-boot.org/en/latest/board/rockchip/rockchip.html#building) fails with the following error.

  LD      /home/andrew/arm-u-boot/trusted-firmware-a/build/rk3399/release/bl31/bl31.elf

I'm using a VM freshly installed with ubuntu 24.04 and crossbuild-essential-arm64 gcc-arm-none-eabi binutils-arm-none-eabi. I'd appreciate any pointers.
