>From the autoconf manual (emphasis mine):

  [The build, host, and target] default to the result of running
  config.guess, unless you specify either --build or --host. In this
  case, the default becomes the system type you specified.
  ***If you specify both, and they're different, configure enters cross
  compilation mode***, so it doesn't run any tests that require execution.
  
  Hint: if you mean to override the result of config.guess, prefer --build over
  --host. In the future, --host will not override the name of the build system
  type. Whenever you specify --host, be sure to specify --build too.
