-可以看到工具链调用的是 `/usr/bin` 下的。这里每个人的情况可能会有所不同，需要额外添加配置选项，指定工具链的可执行程序路径。在这里，我采用修改 `configure.ac` 的方案，通过往 `configure.ac` 中添加相应的配置选项达成目的。具体而言，我在 `configure.ac` 中加入 `--with-toolchain-bindir=<dir>` 这一配置选项，并把其值传递给变量 `$(toolchain_bindir)`，供 `Makefile.in` 使用。
+可以看到工具链调用的是 `/usr/bin` 下的。这里每个人的情况可能会有所不同，所以我们看一下有无相关的配置选项。实际上，我们在之前的探寻过程中已经发现了一个可用的变量：`$prefix`。在 `./configure` 里面，`$prefix` 变量被追加到 `$bindir` 的开头，因此我们只需使用 `$bindir`。另外，elf2flt 中有一个变量 `$DESTDIR`，是指定 Buildroot 中 host 工具链的，为了保持与 Buildroot 的兼容性，我们还需要在 `$bindir` 前面加上这个变量。
 
-`configure.ac` 中修改如下：
