Bug 368470

When trying to building ext_qt 3rd party dependency for OSX 10.11.6, it fails. 

Reproducible: Always

Steps to Reproduce:
1. Installed git, cmake and xcode
2. Created top level directory and set it to BUILDROOT
3. Cloned krita repository
4. Created build, download and install directories
5. Entered the BUILDROOT/b directory
6. Ran 'export PATH=$BUILDROOT/i/bin cmake ../krita/3rdparty/ \ -DCMAKE_INSTALL_PREFIX=$BUILDROOT/i \ -DEXTERNALS_DOWNLOAD_DIR=$BUILDROOT/d \ -DINSTALL_ROOT=$BUILDROOT/i'
7. Ran 'cmake --build . --config RelWithDebInfo --target ext_qt'
8. Experienced the error in the logs

Actual Results:
