The rv64 buildbots run `ninja check-libc` and there were some failures because of #107607, as clang fails to generate an `fmv` instruction; as of clang 19 no fix landed for the issue.

Can you run all the tests with fullbuild enabled for rv64? The last time I tried (a couple of weeks ago), this failed on my visionfive board (rv64).
