>    devel/llvm14: fix build with libc++ 19
>    
>    As noted in the libc++ 19 release notes [1], std::char_traits<> is now
>    only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
>    instantiation for other types will fail.
>    
>    This causes devel/llvm14 to fail to compile with clang 19 and libc++
>    19, resulting in errors similar to:
>
