LCC: for OpenMP, collectly determine implicit link dirs
It is found out for LCC to not specify all library search paths
when called by cmake_parse_implicit_link_info().
Because of that, FindOpenMP module can't find some libraries,
like libpthread. For this, we should analyze -print-search-dirs
output and append library paths to implicit link ones.
