Hello Sam, the problem with just doing that is that xoscons can fail but still leave fragmentary output, and then next time you build make sees that the output file exists and doesn't try rebuilding it. Using && would cause make to fail at the error, but we still need to guarantee the partial output file is deleted, otherwise the next build will not try rebuilding the xoscons outputs and will error some time later when it reuses the fragmentary output while attempting to compile the runtime library. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40984
