[OE-core] [RFC] About GPLv2's native recipe

[Robert Yang]

Hello,

We have several GPLv2 recipes such as m4-native_1.4.9.bb, while we also
have GPLv3's m4-native_1.4.17.bb, I think that we can remove
m4-native_1.4.9.bb if the target m4_1.4.9.bb builds well ?

I'd like to remove it because we don't build the lower native version by
default, and we don't know whether it works or when it would fail.
