1838         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1839         and linking.  Instead of linking in libopcodes.a, just compile
1840         d10v-opc.o directly to handle canadian cross.
1841         (CSEARCH): Add opcodes directory.
1842
1843         * configure.in (--enable-sim-cflags): New switch to allow user to
