As a workaround, you can add CC="$(HOSTCC_NOCCACHE)" to the build commands of host-zlib. But I don't particularly like it. Another option is to force ccache to use its bundled zlib, by adding ccache_cv_zlib_1_2_3=no to HOST_CCACHE_CONF_ENV. The best option would be to check in support/dependencies if the system has a good zlib, and only build host-zlib if it doesn't. But that's major surgery in the build system again.
