PR79017 workaround incomplete C99 math on darwin
PR libstdc++/79017
* acinclude.m4 (GLIBCXX_CHECK_C99_TR1): Check for llrint and llround
functions separately on darwin and if they're missing define
_GLIBCXX_NO_C99_ROUNDING_FUNCS.
* config.h.in: Regenerate.
* configure: Regenerate.
* include/c_global/cmath [_GLIBCXX_NO_C99_ROUNDING_FUNCS] (llrint)
(llrintf, llrintl, llround, llroundf, llroundl): Do not define.
