With any compiler you can use -m flags. With Apple GCC, llvm-gcc, clang, and FSF GCC 4.7 and later, for C and C++ code, you can use -arch flags. MacPorts knows this and sets configure.XX_archflags correctly based on what configure.compiler is; the problem is with the gfortran recipe we’re not setting configure.compiler so configure.ld_archflags could still include -arch flags even though gfortran doesn’t support them.
