It's admittedly extremely unlikely that the host platform name would
contain special characters, but still use double quotes to pattern
matching.

Consider this script:

  #!/bin/bash

  bar="foobar"
  foo="foo*"

  [[ $bar == $foo ]] && echo "first true"
  [[ "$bar" == "$foo" ]] && echo "second true"

We get the output:

  first true

The plan is to move from first case to the second case to prevent
pattern match where there shouldn't be any.
