You're right that the symbols file is currently wrong, but IMO gcc should have
decimal float support enabled for kfreebsd-amd64. It's enabled for
kfreebsd-i386 by virtue of the fact that i?86*-*-gnu* (for Hurd) matches
kfreebsd-i386's tuple, but there's no corresponding x86_64*-*-gnu* for a future
64-bit Hurd, and thus kfreebsd-amd64's tuple is not matched[0].
