Add a universal option to the osx flag, does not work yet since scons strips out the -arch flag that it thinks is a duplicate, add to linker flags since cross compiling on OSX was failing since it was trying to link everything as the wrong arch. Re-Enable the loadstores in 32bit Dolphin in OSX, due to the reason described in the comments (Fast 32bit OSX!). Add an alert if the memory space ends up above 32bit in *nix sides, since it will ALWAYS be above in 64bit OSX, Will try to fix.
