编译出错：

1）checking for suffix of object files... configure: error: in `/opt/embedded/build-tools/build-glibc':

解决方法：PATH=$PREFIX/binPATH ../glibc-2.13/configure BUILD_CC="gcc" CC=arm-linux-gcc --host=$TARGET --target=$TARGET --prefix=/usr --enable-add-ons --disable-profile --cache-file=config.cache --with-binutils=$PREFIX/bin/ --with-headers=$TARGET_PREFIX/include/ ，在配置前面加上PATH=$PREFIX/binPATH ，虽然你可能已加到bash.bashrc或/etc/profile，即将编译成的arm-linux-gcc设置了环境变量,用arm-linux-gcc -v检查发现已存在，但就是不好使，编译会报错（上述），故在配置前面加上此句。
