    Improve OpenMP detection in configure.ac · 254bd8ef

    Some users where "clever" enough to supply a library in LDFLAGS/LIBS
    thath contained omp_get_num_threads, therefore tricking configure into
    thinking that we do not need any flags to enable OpenMP.
    
    Now the Fortran test only works if "use omp_lib" and "!$" OpenMP
    conditional compilation work.
    
    Also, if no valid OpenMP flag could be detected configure silently
    continued. I changed this to an explicit error.
