Just to be clear, the main role of scan-build and ccc-analyzer is to interpose on the build and run the analyzer on each file by executing 'clang'.  Information about specific targets, including processing command line options, should be put in clang, not scan-build or ccc-analyzer.  Beyond being the only solution that will likely work in practice, it pays dividends in the future when bringing up the Clang compiler on the same platform.
