The provider for the host-luainterpreter is always host-lua, never
host-luajit::

    config BR2_PACKAGE_PROVIDES_HOST_LUAINTERPRETER
        string
        default "host-lua"

So, if the host and target variants of EFL need to be built with/against
the same lua interpreter, that would not work.

So, must ELF target and host variants be built with thwe same Lua
interpreter?

Romain, any insight?
