gcc: Pull in libstdc++ long double math function support fix

stephanosio · stephanosio · commit ff344f062119 · 2022-11-17T17:02:49.000+09:00
This commit pulls in the GCC commit that makes the long double math
function support in the libstdc++ &lt;cmath&gt; header an optional feature
such that the C99 math functions are available in the header when
libstdc++ is compiled with a C library that does not provide the long
double math functions  (e.g. newlib).
