 Subject: Define _LIBCPP_HAS_C8RTOMB_MBRTOC8
 
 LLVM libcxx does not define the `char8_t` related functions, instead
@@ -19,14 +19,14 @@ time to implement a proper solution, one needs to create logic to detect
 the picolibc version and define the macro accordingly. The macros that
 govern picolibc version are in `picolibc.h`.
