makefile: For modern, use -fno-strict-aliasing

Browse Source 
So much type-punning causes things to not work on modern compilers. Additionally, -fno-toplevel-reorder is only needed for files with COMMON, as otherwise gcc will break this, so only have them for the two files that need it.

Resulting rom tested on real hardware and mGBA.
