Support configure for generic linux. v5.0.145, v6.0.32 (#3445)

If your OS is not CentOS, Ubuntu, macOS, cygwin64, run of configure will fail with:

```
Your OS Linux is not supported.
```

For other linux systems, we should support an option:

```
./configure --generic-linux=on
```

Please note that you might still fail for other issues while configuring or building.
