LI Qing 1304f5388d Improve Occlum GCC toolchain with new wrappers for binaries 
This commit makes the toolchain easier to use in two folds:
1. When compiling C/C++ source files, no need to add "-fPIC -pie" flags manually;
2. When running executables generated by the Occlum toolchain on Linux, no
need to set the `LD_LIBRARY_PATH` manually.

A Sample C Project with Makefile and CMake

This project demonstrates how to use Makefile/CMake to build C projects for Occlum.

  1. Build hello_world with Makefile
make

Or you can build hello_world with CMake

mkdir build && cd build
cmake ../ -DCMAKE_C_COMPILER=occlum-gcc
make
cd ..
cp build/hello_world .

Either way, the resulting hello_world can be found in the current directory.

  1. (Optional) Run hello_world on Linux
./hello_world
  1. Run hello_world on Occlum
mkdir occlum_workspace && cd occlum_workspace
occlum init
cp ../hello_world image/bin
occlum build
occlum run /bin/hello_world
