LiteOS2021 dc9ec6856f feat: L0-L1 支持Trace 
1.【需求描述】
            L0~L1 支持Trace，提供两种工作模式：在线模式、离线缓存模式， 用于按时间线追踪系统事件，如任务切换、中断、ipc等。
        2.【方案描述】
            L0:
            (1).在内核模块预置静态代码桩
            (2).触发桩后，收集系统上下文信息
            (3).离线模式则写入内存，用户可通过dump导出；
            (4).在线模式通过pipeline对接IDE进行可视化解析和展示；
            L1:
            新增trace字符设备，位于"/dev/trace",通过对设备节点的read\write\ioctl，实现用户态trace；

        BREAKING CHANGE:
        1.新增一系列trace的对外API，位于los_trace.h中.
        LOS_TRACE_EASY简易插桩
        LOS_TRACE标准插桩
        LOS_TraceInit配置Trace缓冲区的地址和大小
        LOS_TraceStart开启事件记录
        LOS_TraceStop停止事件记录
        LOS_TraceRecordDump输出Trace缓冲区数据
        LOS_TraceRecordGet获取Trace缓冲区的首地址
        LOS_TraceReset清除Trace缓冲区中的事件
        LOS_TraceEventMaskSet设置事件掩码，仅记录某些模块的事件
        LOS_TraceHwiFilterHookReg注册过滤特定中断号事件的钩子函数

Guangyao Ma 77dcef4bc0 fix: clang相关编译选项隔离 
liteos_a在apps/mksh和apps/toybox编译中，clang相关编译选项未进行隔离。之后支持
其他类似gcc编译时，可能存在编译问题。
其中 --target=$(LLVM_TARGET) $(LLVM_SYSROOT) 是clang编译特有的编译选项，需要被
隔离。

Guangyao Ma 7819d15b36 fix: 去掉冗余的strip操作 
toybox源码编译时，默认会进行strip操作，如下步骤：

//third_party/toybox/scripts/make.sh:340:
! do_loudly ${CROSS_COMPILE}${STRIP} "$UNSTRIPPED" -o "$OUTNAME"

因此在打包的Makefile中再进行STRIP操作是冗余的。

Guangyao Ma 565b2e85cd refactor(mksh): reduce the mksh size by Oz 
clang不支持“-flto,-Oz”作为链接选项，但是可以作为编译选项，且作为编译选项时，有更好的size减少效果。这里为了使用这种
编译选项组合，且为了不影响链接过程（Build.sh链接时也会使用CFLAGS），在链接选项生效的-O选项中，重置其为O2。
最终size可以从300+k,缩减为不到180k。
