On my machine, "llvm-config --ldflags" outputs:
-L/usr/lib/llvm-3.4/lib  -lpthread -lffi -ltinfo -ldl -lm

But configure filters only -L arguments into LLVM_LDFLAGS. The rest of 
the -l flags above are already present on the libjvm link line, but 
before $(LLVM_LIBS). If I explicitly add -ltinfo last on the link line 
(after LLVM_LIBS), my build succeeds.
