Unable to compile IcedTea with CACAO under Fedora 17

> Some numbers (SciMark is far from my favourite but it runs quickly):

I couldn't resist trying out my new armhf build, on armv7. And
finally, after CACAO has not exactly excelled in recent benchmarks,
these numbers are quite nice. CACAO uses only ARM instructions, not
Thumb. I am aware the two results below are not exactly comparable, as
they are completely different versions of OpenJDK, but in my
experience this doesn't usually make a significant difference. I'll
follow once I've got builds carrying the same versions.
