Problems with zlib

Hi,

I'm trying to build tinyX using buildroot snapshot 18532 with a external toolchain, although i was able to build zlib, it seems that installation step is wrong because when building tinyX i get this message:

/home/dfons/toolchain-nihilisme/arm-unknown-linux-gnu/bin/arm-unknown-linux-gnu-gcc

collect2: ld returned 1 exit status
make[5]: *** [Xfbdev] Error 1
make[5]: Target `all' not remade because of errors.

It is not the headers bug which was described in previous mail, here ld can`t locate the zlib library. Is this another bug? how can i fix it?

I attach the .config file.
