Build Premake5 From Source

1. Problems:

   1. The lastest released binary premake-5.0.0-beta7 requires GLIBC_2.38

      Commands of installing prebuilt bin

      {{{ ```shell # Quick option: download a premake5 binary wget https://github.com/premake/premake-core/releases/download/v5.0.0-beta7/premake-5.0.0-beta7-linux.tar.gz tar -xzf premake-5.0.0-beta7-linux.tar.gz sudo mv premake5 /usr/local/bin/ premake5 --version ``` }}}

      The binary premake5 is not usable due a GLIBC mismatch:
