m68knommu: fix strace support for 68328/68360
strace enabled is marked using the `flags' field of the `thread_info' struct. 68360 version of entry.S did test a wrong bit in a wrong structure (task_struct). 68328 version of entry.S did test the right bit in the right structure, but wrongly, because the `flags' field is 32 bit wide, while the used assembler insn (btst) only accesses a 8 bit byte in memory. Fix both using code already used in the coldfire version of entry.S Signed-off-by: Philippe De Muyter <phdm@macqel.be> Signed-off-by: Greg Ungerer <gerg@uclinux.org>
