The following patch defines sigcontext ABI of ColdFire. Due to ISA restrictions ColdFire needs different rt_sigreturn trampoline. And due to ColdFire FP registers being 8-bytes instead of 12-bytes on m68k, sigcontext and fpregset structures should be updated. Regarding the sc_fpstate[16+6*8] field, it would've been enough 16 bytes to store ColdFire's FP state. To accomodate GLIBC's libSegFault it would'be been enough 6*8 bytes (room for the 6 non-call-clobbered FP registers). I set it to 16+6*8 to provide some extra space for any future changes in the ColdFire FPU.
