Some of the required relocations for LLVM on aarch64 (ELF) are missing. Furthermore, some of the WAST tests related to SIMD instructions fail, for example:

--- STDERR:              wasmer-workspace::compilers wast::spec::simd_lane::llvm::universal ---
Error: Failed directives on tests/wast/spec/simd_lane.wast:
