When i try to compile darktable with -fsanitize=memory, linking fails.          

[ 18%] Linking C shared library libdarktable.so
/usr/bin/ld: error:
/usr/lib/llvm-3.9/lib/clang/3.9.0/lib/linux/libclang_rt.msan_cxx-x86_64.a(msan_new_delete.cc.o):
requires dynamic R_X86_64_PC32 reloc against '_ZN6__msan11msan_initedE' which
may overflow at runtime; recompile with -fPIC


cmake call:                                                                     
LDFLAGS="-fsanitize=memory" CFLAGS="${LDFLAGS}" CXXFLAGS="${LDFLAGS}"
CPPFLAGS="${LDFLAGS}" CC=clang-3.9 CXX=clang++-3.9 cmake ../                    

make VERBOSE=1 shows that it tries to link to                                   
/usr/lib/llvm-3.9/lib/clang/3.9.0/lib/linux/libclang_rt.msan_cxx-x86_64.a       

I have tried looking for .so, but i see none in                                 
$ dpkg -L libclang-common-3.9-dev | grep msan | grep so
