For a quick test, I cloned the board/amlogic package into an existing 
buildroot-git instance (2023.02-100-g9833247d49). In the build directory 
I ran:

wget 
https://raw.githubusercontent.com/mathieu-lm/libretech-cc-buildroot/master/configs/meson-gxl-s905x-libretech-cc_defconfig
mv meson-gxl-s905x-libretech-cc_defconfig .config
make nconfig
make uboot

It builds successfully:

>>> uboot v2020.01-rc5 Installing to target
>>> uboot v2020.01-rc5 Installing to images directory
cp -dpf /home/data/test/autobuild/build/uboot-v2020.01-rc5/u-boot.bin 
/home/data/test/autobuild/images/

You seem to use a different u-boot version than specified in the 
original configuration. You might need to update the u-boot defconfig in 
board/amlogic/s905x-libretech-cc/uboot and probably also the toolchain 
(currently gcc 6 based, from 2017).

Kind regards,
Andreas
