通常情况下，tooldir (可执行文件最后安装到的目录) 是 $(exec_prefix)/$(target_alias), 如果展开，就成为类似于 /usr/i686-pc-linux-gnu这样。因为我们只为自己的系统编译，就并不需要/usr目录下再存在目标前缀。它是在交叉编译时(比如在Intel机器上编译将在PowerPC上执行的程序时)才用到的。
make install_root=${TARGET_PREFIX} prefix="" install
(You can install glibc somewhere other than where you configured it
to go by setting the install_root' variable on the command line for<br />make install’. The value of this variable is prepended to all the
paths for installation. This is useful when setting up a chroot
environment or preparing a binary distribution. The directory should be
specified with an absolute file name.)
patch -Np1 -i ../gcc-3.3.1-specs-2.patch
补丁修改gcc的缺省动态连接器ld-linux.so.2的位置，还把/usr/include从GCC的头文件搜索路径里删掉。在安装前打补丁，可以保证新的动态连接器在编译gcc的时候就用上。也就是说，随后的所有临时程序都会连接到新的glibc上。
make -C ld LDFLAGS="-all-static" LIB_PATH=/tools/lib
-C ld LDFLAGS="-all-static" LIB_PATH=/tools/lib: LIB_PATH是 makefile 中的一个变量，在命令行里指定它，使我们可以覆盖缺省值，让它指向我们的临时工具目录。这个变量的值就是连接器的缺省库搜索路径。(If you want to make a cross-linker, you may want to specify a different search path of -lfoo libraries than the default.
You can do this by setting the LIB_PATH variable in ./Makefile or using the –with-lib-path configure switch.)
