That should be in the ncurses-devel package (or whatever it's called on
Ubuntu) which I thought was an OpenJDK requirement anyway. Maybe the
only problem is that we're not linking with -lncurses.
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.
