I get the same error emerging sys-devel/clang-18.1.8. My system is Asus TinkerBoard S (arm cortex A17). My llvm was built with cross-emerge on a x86, because the board doesn't have enough memory to build llvm even with -j1.

Also happens for me with 18.1.8 on x64 machine.
I realized that this problem happens only package is compiled by GCC. Adding back recommended USE="+clang" (which instead compiles it by CLANG) make it working fine.
