Currently, the compiled output of BE mainly consists of two binaries:
palo_be and meta_tool, which are both around 1.6G in size.
However, the debug information is only needed for debugging purposes.
So I separate the debug info from binaries.
After BE is built, the debug info file will be saved in `be/lib/debug_info/` dir.
`palo_be` and `meta_tool`'s size decrease to about 100MB
This is optional, and default is disabled.
To enable it, use:
`STRIP_DEBUG_INFO=ON sh build.sh`

Doris BE development and debugging environment construction
Add installation under ubuntu, dependent installation
Compile on ubuntu 20.04 physical machine, the actual test needs to install these dependencies:
autoconf automake libtool autopoint
1. fix build thirdparty may be failed in some os, because of default lib path is `lib` or`lib64` or `arrow` bulld failed by `brotil` and `zstd`
