[PATCH] sim: cr16: add ifdefs around undefined syscalls

The cr16 libgloss port does not define these syscall numbers, so trying
to use them results in build failures [1]. The cr16 code already uses
ifdefs around a bunch of syscalls, so extend that style to cover the
ones that are currently missing. Now we can at least compile.
Committed.

* simops.c (OP_C_C): Only handle TARGET_SYS_fork, TARGET_SYS_execve,
TARGET_SYS_pipe, TARGET_SYS_rename, and TARGET_SYS_chown when they
are defined.
