Alright, so I just checked out trunk and although I see the patch you
sent is already in place in mono/mono/mini/mini-trampolines.c I get the
exact same error:
17:41|melis at juggle2:~/c/mono-svn/mono/mono/mini> make

This seems to be caused by MONO_ARCH_LLVM_SUPPORTED not being set,
bringing me back to a previous question: is Mono + LLVM supported on
32-bit x86? As I see this:
17:42|melis at juggle2:~/c/mono-svn/mono/mono/mini> grep
MONO_ARCH_LLVM_SUPPORTED *
mini-amd64.h:#define MONO_ARCH_LLVM_SUPPORTED 1
mini-arm.h:#define MONO_ARCH_LLVM_SUPPORTED 1
