    libstdc++: Only use __builtin_sprintf if supported [PR 96083]

    Clang doesn't support __builtin_sprintf, so use std::sprintf instead.

    libstdc++-v3/ChangeLog:

            PR libstdc++/96083
            * include/ext/throw_allocator.h: Use __has_builtin to check for
            __builtin_sprintf support, and use std::sprtinf if necessary.
