This TN describes exactly what I am doing: passing -arch flags in compiler flags. However, this does not work with libusbx, apparently because those flags are passed to a cc -E or -M command. An example showing the issue is:
% cc -E -arch i386 -arch x86_64 llvm-gcc-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags % Which makes sense given that the preprocessor output might differ between the two architectures. The solution might be to file a bug against automake or libtool or etc. which probably should rely on CPPFLAGS only when calling $(CC) with -E or -M.
