Rollup merge of #132150 - taiki-e:ppc64-freebsd-abi, r=pnkfelix 
Fix powerpc64 big-endian FreeBSD ABI

Note that FreeBSD version bump may be reverted due to https://github.com/rust-lang/rust/pull/120869#issuecomment-2438685835. We may want to wait to merge this until that discussion is complete.

This also makes the binaries from previous FreeBSD versions incompatible with 13.0-RELEASE. Kernel still supports ELFv1, so jails and chroots using older FreeBSD versions are still compatible.
