package/libs/zlib: Add option for O3 optimization
Add option to use O3 optimization as not all devices have space constraints. This option is default using GCC in upstream but isn't in the CMake makefile for some reason. Source: https://github.com/madler/zlib/blob/master/configure#L170 Signed-off-by: Daniel Engberg <daniel.engberg.lists@pyret.net>
