Implement double pass of the relevant Makefiles. First make a list of library names and directories and then scan for all the dependencies. Spaces in directories in the source tree are not supported. This avoids using hardcoded mappings between the library name and the directory containing the library Makefile. Add support for scanning contrib/ofed . Bail out on any errors.
