With llvm 2.5 the JVM immediately crashes. However that reminded me of the
situation when I got sharkt to work with llvm 2.4 first.

The trouble is that shark cannot cope with the situation in which it does not
get a default JIT compiler. If it is not available it will simply segfault
(since the respective variable holding the JIT compiler instance is null).

The reason for the JIT compiler not being there is very simple: The object code
containing it was not linked in. :(

In LLVM 2.5 they changed what 'llvm-config --libs' returns again. Now
'nativecodegen engine' does not contain machine-specific stuff anymore. You
need to tell it 'armcodegen' or the like.

I think it is inconvenient for icedtea's configure to contain the logic to pull
in the right backend. I will file a bug at llvm's BT and see whether they can
do it like it was before.
