编译uboot提示libz.so.1找不到

如题，我编译uboot提示libz.so.1找不到。
/opt/Embedsky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/bin/../libexec/gcc/arm-fsl-linux-gnueabi/4.6.2/cc1: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

find了下，系统里有这个库。
./lib/x86_64-linux-gnu/libz.so.1
./usr/lib/vmware-tools/lib32/libz.so.1
./usr/lib/vmware-tools/lib32/libz.so.1/libz.so.1
./usr/lib/vmware-tools/lib64/libz.so.1
./usr/lib/vmware-tools/lib64/libz.so.1/libz.so.1

请大家指点下，应该怎么设置。谢谢
