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。

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。
