Fixes #5949

getconf LONG_BIT is POSIX-complient and thus should work on any Unix-like systems (including cygwin)

Tested successfully on Linux, macOS, Cygwin and MSYS2

Thanks for this!! That means that switches on Raspberry Pi OS now install host-arch-arm32 instead of host-arch-arm64 with https://github.com/ocaml/opam-repository/pull/25861.

This seems a sensible change to me?
