 Build log attached.

 When building sane-backends on lion, the build fails with the error
 “:info:build llvm-gcc-4.2: -E, -S, -save-temps and -M options are not
 allowed with multiple -arch flags”.

 Building with “-universal” doesn't help me because various other ports are
 already installed with “+universal” which seems to get merged in. I'd
 rather not have to ununiversalise all the dependent ports (of which there
 are many!), but have this port fixed to work universal!
