zlib compression was introduced in version 9.3.3. However, when
cross-compiling kmscon for an architecture other than x86_64, the
genunifont executable tries to use the build-systems zlib instead
of the hosts zlib.
This leads to the following error during compiling:
libz.so: error adding symbols: file in wrong format
Fix this by adding a new native zlib dependency specifically for the
genunifont executable.
