x86 libs not included in production APK

I have this error with an x86 android device :

06-24 16:53:27.581: E/TiApplication(26733): (KrollRuntimeThread) [243,439] Sending event: exception on thread: KrollRuntimeThread msg:java.lang.UnsatisfiedLinkError: Couldn't load stlport_shared: findLibrary returned null; Titanium 3.1.0008,2013/05/20 15:16,13dc078

The lines responsible for this error are included in the Titanium build code android/builder.py :

for abi in self.abis:
            lib_source_dir = os.path.join(sdk_native_libs, abi)
            lib_dest_dir = 'lib/%s/' % abi
            if abi == 'x86' and ((not os.path.exists(lib_source_dir)) or self.deploy_type == 'production'):
                # x86 only in non-production builds for now.
                continue

When I remove the if condition, the app works fine.

Does someone know if it's safe to remove these lines or if any other solution exists?
