You could just patch cstddef, e.g. something like:

diff --git a/libstdc++-v3/include/c_std/cstddef b/libstdc++-v3/include/c_std/cstddef
index f4845f024329..f12570e53947 100644
--- a/libstdc++-v3/include/c_std/cstddef
+++ b/libstdc++-v3/include/c_std/cstddef
@@ -48,7 +48,9 @@
 namespace std
 {
   // We handle size_t, ptrdiff_t, and nullptr_t in c++config.h.
+#ifndef __clang__
   using ::max_align_t;
+#endif
 }
 #endif
