Merge #20478: Don't set BDB flags when configuring without

982e548a9a Don't set BDB flags when configuring without (Jonas Schnelli)

Pull request description:

  Configuring `--without-bdb` on MacOS leads to a compile error (when BerkeleyDB is not installed). `brew --prefix berkeley-db4` always reports the target directory (even if not installed).

  This PR prevents BDB_CFLAGS (et al) from being populated when configuring `--without-bdb`
