graphics/decker - drop -Werror to fix build on sparc64

decker fails immediately when building on sparc64 with

./c/lil.h:112:60: error: ISO C forbids conversion of function pointer to object pointer type [-Werror=pedantic]

Patching Makefile to drop "-Werror" allows decker to build on sparc64

ok?
