How good are you with reading/editing Makefiles? I find problems like this are usually solved by searching the Makefiles for the offending line(s) and removing the offending switch.
In a well-designed make environment, you should only have to edit the top-level Makefile. In the worst case, you'll have to edit every Makefile. Fortunately, you can usually speed this up with some shell kung-fu, if necessary. This of course doesn't work if the developers were "clever" enough to have a build environment that overwrite the Makefiles with new ones every time to try to build. I don't think this applies to Open MPI.
