Looks like multilib support in libgrust is just broken. I suspect it would be
worse on other targets where there are many more multilibs.

    libgrust: 'AM_ENABLE_MULTILIB' only for target builds [PR113056]

    ..., but not for host builds, which don't need it, and it may cause the
build
    to fail.

    Use what appears to be the standard pattern for that (see
    'libbacktrace/configure.ac', 'zlib/configure.ac').

            PR rust/113056
            libgrust/
            * configure.ac: 'AM_ENABLE_MULTILIB' only for target builds.
            * configure: Regenerate.
