As all OMP related symbols will then be resolved at compile time, it doesn't matter that gcc declares `libgomp.so` and clang `libomp.so` respectively as NEEDED. Further I'll disable building llvm openmp when statically linking to `libiomp.so`. @cjolivier01 does that sound alright to you? Linking to omp statically is dangerous because atfork handler registration (and thus execution) order is no defined, as well as general global init order, of course, although I am not sure if that is problematic since libiomp i all C.
