[yocto] fontconfig-native build error

[Craig McQueen]

I've been building a project with 'morty' with no problems for a few months, using Ubuntu 16.04.

Today, I've just tried doing a build on a fresh Ubuntu 17.10 VM. But I'm getting a build error for fontconfig-native:

Funnily enough, fontconfig (not native) builds fine; it's only fontconfig-native that gives the above error.

Any advice on this? I would consider going back to Ubuntu 16.04; I would also consider moving from morty to pyro or rocko (it's on my to-do list).
