Do you have the -dev package of zlib? Also for 64-bit?

On a CentOS system, I have seen a problem with the static version of
zlib missing, when building a static toolchain with crosstool-ng. On
CentOS, the static version (libz.a) is distributed as a separate
package. I don't know if this is the case on your system.

Best regards,
Thomas
