标题: 请教一个交叉编译器的问题
按照CLFS在ubuntu12.10上搭建ARM的交叉编译工具链。GCC版本4.7.2。
最后完整编译GCC的时候，出现个很奇怪的的问题，提示有3个lib找不到，但是这些库已经存在。
从错误信息上看，是路径设置错误了。可是不知道应该加什么选项来设置。
环境变量：
CLFS=/home/long/Tool/CrossTool
配置选项如下：
R=ar LDFLAGS="-Wl,-rpath,/home/long/Tool/CrossTool/cross-tools/lib" \
../gcc-4.7.2/configure \
      --prefix=/home/long/Tool/CrossTool/cross-tools       \
      --build=${CLFS_HOST}                                  \
      --target=${CLFS_TARGET}                               \
      --host=${CLFS_HOST}                                  \
      --with-sysroot=${CLFS}                               \
      --with-native-system-header-dir=/tools/include       \
      --with-local-prefix=/home/long/Tool/CrossTool/tools    \
      --disable-nls                                        \
      --enable-shared                                        \
      --enable-languages=c,c++                               \
      --enable-__cxa_atexit                                  \
      --with-mpfr=/home/long/Tool/CrossTool/cross-tools    \
      --with-gmp=/home/long/Tool/CrossTool/cross-tools       \
      --enable-c99                                           \
      --with-ppl=/home/long/Tool/CrossTool/cross-tools       \
      --with-cloog=/home/long/Tool/CrossTool/cross-tools    \
      --enable-long-long                                     \
      --enable-threads=posix                               \
      --disable-multilib
编译命令：
make AS_FOR_TARGET="${CLFS_TARGET}-as" LD_FOR_TARGET="${CLFS_TARGET}-ld"
错误信息如下：
/home/long/Tool/CrossTool/cross-tools/bin/arm-none-linux-gnueabi-ld: cannot find /home/long/Tool/CrossTool/tools/lib/libc.so.6 inside /home/long/Tool/CrossTool

sysroot和local-prefix叠加了
