    misc/codex: fix build on powerpc64*
    
    Build V8 without the sandbox and Maglev on powerpc64, which its PPC64
    backend does not support, let clang use its own target on FreeBSD
    instead of the Linux triple, add the ppc64 clang toolchain, require
    POWER8 vectors for simdutf's PPC64 kernel as upstream does and carry
    node's big-endian byte order, ELFv2 and sampler fixes.
