m68knommu: disable MC68000 cpu target when MMU is selected
As pointed out by Geert, MC68000 target needs to be disabled when MMU support is enabled. From Geert: This needs a "depends on !MMU". Else allmodconfig will select it, causing -m68000 to be passed to the assembler, which may break the build depending on your version of binutils, a.o. arch/m68k/kernel/entry.S:186: Error: invalid instruction for this architecture; needs 68020 or higher (68020 [68k, 68ec020], 68030 [68ec030], 68040 [68ec040], 68060 [68ec060]) -- statement `bfextu %sp@(50){#0,#4},%d0' ignored arch/m68k/kernel/entry.S:211: Error: invalid operand mode for this architecture; needs 68020 or higher -- statement `jbsr @(sys_call_table,%d0:l:4)@(0)' ignored Cfr. http://kisskb.ellerman.id.au/kisskb/buildresult/7416877/ Signed-off-by: Luis Alves <ljalvs@gmail.com> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
