我如何安装32位版本的Google的NaCl SDK？

我正在pepper_46尝试使用Google的Native Client SDK，所以我已经下载了安装，安装和尝试构建“入门”项目的工具，我得到了以下响应。

据我所知，相关部分是[Errno 8] Exec format error和Command was: /home/rob/.../bin/clang。经过一番调查，我发现了这一点。

rob@asmodeus:~/Downloads/nacl_sdk/pepper_46/toolchain/linux_pnacl/bin$ file clang
clang: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.24, BuildID[sha1]=a828789c24cefbb485103da1bf609d35e447dda2, stripped
rob@asmodeus:~/Downloads/nacl_sdk/pepper_46/toolchain/linux_pnacl/bin$

令人担忧的部分是“x86-64”，因为我的系统是一个简单的x86系统！Google的安装SDK的页面声明它支持x86-32，但没有说明如何操作，我无法在任何地方找到32位二进制文​​件或安装它们的方法。如何获取32位这些文件集？

在做了一些更多的研究之后，我发现即使Google确实支持x86-32 for NaCl，他们也不支持SDK。
