make: *** [build/SDL_render_metal.lo] Error 1

This was on OS X 10.14 with the 10.11 SDK but I first encountered this on a real 10.11 machine.
MACOSX_DEPLOYMENT_TARGET=10.7
Comment 1 Dominik Reichardt 2019-10-17 07:10:12 UTC 
Deployment Target does mot factor in, I just tested.
SDKs 10.12 and higher do not have a problem at this point.

Thanks for the report, this change should fix it: https://hg.libsdl.org/SDL/rev/d36bfafbe115
