Because VxWorks doesn't support building LTP test library now, I need find a new way to support this patch.
The old version fsx-linux.c can be built alone on VxWorks and used in VxWorks user space because it mostly calls POSIX APIs.
I will take some time to investigate if VxWorks can support LTP test APIs.

Xin
