patch add mini backtrace (#416)
* support rust panic backtrace

mini-backtrace has llvm's unwind cpp source to support backtrace/unwind.
as unwind/backtrace needs dynamically allocates memory, mini-backtrace
uses stack memory to capture fixed number of backtrace to avoid heap
allocation.
as unwind library needed, it needs to turn on eh_frame_hdr

* 修改忘了生成kernel.elf的问题

* 设置backtrace是默认的feature
