But you might still consider adding a case statement in the gcc_no_link branch seeding the correct defines or the respective configure cache variables (ac_cv_lib_m_cbrtl etc) for targets where the functions are known to be available. For configure choices that are not just used for optimization, of course that becomes required procedure.
