Order of the llvm libs vs ldflags is important
Attached patch detected legacy ok for me and is currently compiling

The huge list of libraries indicates that your LLVM installation doesn't
provide the single shared library. Do you have any shared libraries in
/opt/clang+llvm-3.4.2/lib or only static libs? Did you build llvm with
the --enable-shared option? That might help, with the added bonus that
shared libs on Linux typically link with the libraries that they depend
on, so you don't need to specify the additional libs.

That said there may still be a bug here if someone really does wish to
build Octave against LLVM static libs.
