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. Fixes https://github.com/rust-lang/rust/pull/120869#discussion_r1813233054 > > PPC64 FreeBSD (ELFv1 and ELFv2, version 13.2) > > It seems odd that ELFv1 and 13.N coexist. > > https://www.freebsd.org/releases/13.0R/relnotes/ > > > powerpc64 switched to ELFv2 ABI at the same time it switched to LLVM. This brings us to a parity with modern Linux distributions. 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.
