1.64.0 built fine.
On powerpc-unknown-freebsd:

  = note: /usr/local/bin/ld.bfd: /wrkdirs/usr/ports/lang/rust/work/_build/powerpc-unknown-freebsd/stage0-rustc/powerpc-unknown-freebsd/release/deps/librustc_driver-95f1e4ba1a525000.so: undefined reference to `__atomic_load_8'
          /usr/local/bin/ld.bfd: /wrkdirs/usr/ports/lang/rust/work/_build/powerpc-unknown-freebsd/stage0-rustc/powerpc-unknown-freebsd/release/deps/librustc_driver-95f1e4ba1a525000.so: undefined reference to `__atomic_store_8'
          cc: error: linker command failed with exit code 1 (use -v to see invocation)

Probably related to LLVM upgrade.
