Hello! This is expected error because LLVM does not support e500v1
(8540) powerpc cores. LLVM supports e500v2 (8548) cores via LLVM
target cpu value "e500".
You should switch compiler from LLVM to GCC when compiling Linux for
e500v1/8540 powerpc cores.

Hum ... That should have been fixed with commit 4b10306e9845 ("powerpc:
Disable CPU unknown by CLANG when CC_IS_CLANG")
Apparently I missed it. Maybe because clang supports 8548. Is that
different from 8540 ?

Yes! e500v1 core (named 8540 in gcc) is older version of e500v2 core
(named 8548 in gcc). IIRC e500v2 is backward compatible with e500v1.
