2     clang -c -g -arch x86_64h -arch x86_64 -arch i386 fat-test.c
3     libtool -static -o libfat-test.a fat-test.o

5     to generate a dylib instead:
6     clang -arch ...  -arch ... -arch ...  -dynamiclib fat-test.o -o fat-test.dylib
7  
8     To reduce the size of the fat binary:
9     lipo -thin i386 -o fat-test.i386.o fat-test.o
10     lipo -thin x86_64 -o fat-test.x86_64.o fat-test.o
11     lipo -thin x86_64h -o fat-test.x86_64h.o fat-test.o
12     lipo -create -arch x86_64h fat-test.x86_64h.o -arch x86_64 fat-test.x86_64.o -arch i386 fat-test.i386.o -o fat-test.o -segalign i386 8 -segalign x86_64 8 -segalign x86_64h 8
