Because BR2_PACKAGE_LUA is a provider for the virual package
lua-interpreter, and you should not select a provider of a virtual
package:

    https://buildroot.org/downloads/manual/manual.html#_infrastructure_for_virtual_packages

    If your package really requires a specific provider, then you?ll
    have to make your package depends on this provider; you can not
    select a provider.

(followed byu an example why this should indeed not be done.)

Regards,
Yann E. MORIN.
