    ld: Just xfail riscv little endian targets for compressed1d.d test.
    
    The sizes of compressed and uncompressed .debug_aranges are the same
    for the riscv big endian targets, but different for the little endian
    targets.  The compress rule is fine and isn't broken by riscv, just the
    original compressed1d.d fails by accident.  Ideally, we should fill the
    R_RISCV_ADD/SUB relocations when disabling relaxations in the assembler.
    But before that, Jim already had written an alternative test compressed1d-alt
    to relpace compressed1d.d for riscv, so we can only xfail the riscv little
    endian targets in the short-term.
    
    ld/
        * testsuite/ld-elf/elf.exp (riscv_little_endian): Added.  Return true
        if target is riscv little endian.  Otherwise, return false.
        * testsuite/ld-elf/compressed1d.d: Only xfail the riscv little endian
        targets by [riscv_little_endian].
