clfs中编译cross gcc错误

我在进行第一遍static的gcc编译的过程中出现了如下的错误：
gcc -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -DHAVE_CONFIG_H -I. -I. -I../../gcc -I../../gcc/. -I../../gcc/../include -I../../gcc/../libcpp/include -I/home/yuanbo/moblin-sysroot/cross-tools/include -I/home/yuanbo/moblin-sysroot/cross-tools/include -I../../gcc/../libdecnumber -I../../gcc/../libdecnumber/dpd -I../libdecnumber ../../gcc/vec.c -o vec.o
make[1]: *** No rule to make target `../../gcc/FULL-VER', needed by `version.o'. Stop.
make[1]: Leaving directory `/home/yuanbo/rpmbuild/BUILD/gcc-4.3.3-20081022/build-dir/gcc'
make: *** [all-gcc] Error 2

请问该如何定位啊？
哪里出现了错误？

非常感谢！
