Fixed bug 3460 - docs/README-macosx.md: g++fat.sh should be g++-fat.sh in universal build command

Elisée Maurer

I scratched my head for a while until I realized there's a typo in the command listed in the instructions for universal Mac builds: https://hg.libsdl.org/SDL/file/c1bb718f6c3f/docs/README-macosx.md#l24

It should say `g++-fat.sh` but instead it says `g++fat.sh`, which makes `./configure` fail with a C++ preprocessor error.
