Makefile: Add `-gnatw_R` to suppress spurious warning

Looks like there's a new warning option that complains when the order of
component declarations, component clauses, and bit-level layout do not
all agree. However, we also enable `warnings are errors`. Plus, we use
mismatched component representation clauses on purpose in libgfxinit's
epilepsy-inducing gfxtest program to have RGB ordering on hardware that
works with BGR ordering. Hardware is cursed, so silence this warning.
