Indeed, it is a long-time limitation of using buildroot toolchain as
external ones, all options are not necessarily available in the
external toolchain backend. :-/

In the gcc package, there is some extra checks for fortran with
libquadmath when available (which depends on the target architecture).
So, I wonder whether it should be sensitive to libquadmath (so wchar)
on the relevant architectures.
