I encountered this mid of this year after 2025.07.
The uncompilable distro is Ubuntu 18.04, however once I update
to 20.0x and 22.xx there are no issue anymore.

But I did not deep investigate this issue because distro updated can
resolve this issue. I simply think it is u-boot no longer support old GCC.
Just want to point out the failing point of my experiences.

Thanks,
Brian
