Port truss(1) to 64-bit architectures:

Browse Source 
o  Syscall return values do not fit in int on 64-bit architectures.
   Change the type of retval in <arch>_syscall_exit() to long and
   change the prototype of said function to return a long as well.
o  Change the prototype of print_syscall_ret() to take a long for
   the return address and change the format string accordingly.
o  Replace the code sequence
	tmp = malloc(X);
	sprintf(tmp, format, ...);
   with X by definition too small on 64-bit platforms by
        asprintf(&tmp, format, ...);

With these changes the output makes sense again, although it does
mess up the tabulation on ia64. Go widescreen...

Not tested on: alpha, sparc64.
