Linker ignores.

I am just trying this out. I added -L/usr/lib64/llvm in the relevant
line of dub.json and everything seems to work nicely on Fedora. Sadly
on Debian there is no version independent location for LLVM as far as I
can tell.

"lflags-posix": ["-lclang", "-rpath", ".", "-L.", "-L/usr/lib64/llvm", "-L/usr/lib/llvm-3.7/lib"],

Works on both Fedora and Debian, but it hardwires 3.7.
