[Liboil] Re: liboil issue with float point cross compile?

[Nathan Fain]

hmm, this wouldn't be an issue with the fact that the build machine is
x86?  That is, the cross compiler is running on an x86 machine.  Perhaps
it is referencing the local kernel sources?  Tell me if I'm getting
warmer or colder.
