Order of linking flags needs to be changed for GCC in clangdao

[dumblob]

Likely the same issue as described in https://code.google.com/p/include-what-you-use/issues/detail?id=92 . Right now it's needed to put -lclangEdit before -lclangLex to link with GCC under Linux.

Also, in my case I'm using LLVM 3.5.1 and Clang 3.5.1 and I need to add the whole output of llvm-config --libs after the linking flag -lclangStaticAnalyzerFrontend to link properly (otherwise symbols are missing etc.). According to my understanding, it has something to do with including symbols from clang (which in turn includes symbols from llvm) and llvm at the same time into one object file. I couldn't come up with better solution :(
