Could you give an example situation in which this is needed?  Currently I
just see that user might do misleading things like:

  --host=powerpc-unknown-foo --target=powerpc-unknown-bar

and then the check will think that host != target because foo != bar, without
taking into account that "bar" is meaningless here.
