config: Add package versioning flexibility

Some users (like myself) may want to omit the crosstool-NG version
from the binaries' versioning output, as it can be incredibly long
and not too helpful. Add a config option to disable it. The possible
combinations are as follows:

- crosstool-NG version (default)
- crosstool-NG version - custom toolchain ID
- Custom toolchain ID
- No crosstool-NG version OR custom toolchain ID
