This is actually a very good case in point for 'recursive make considered harmful' . We have individual files in libiberty depending on an individual header file from another library. If instead of all these sub-makes, we had one big make with a makefile that includes all the sub-makefiles so that it can see the dependencies at once, it would be straightforward to specify the exact dependency. I also suspect that the original ordering problem from pr42813 stems from --enable-build-with-cxx introducing some dependency of libgomp on libstdc++-v3, and then make drops one edge from the circular dependency. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36101
