Not matching string with wildcard in if statement

[Jeffrey Walton]

Hi Everyone,

I'm having a problem that I need help with. I think I can't see the
forest through the trees...

I have two env vars:

    export IOS_CPU=armv7s
    export IOS_SDK=iPhoneOS

I then miss the match in a script:

    #!/usr/bin/env bash

    if [[ "$IOS_SDK" == "iPhoneOS" && "$IOS_CPU" == "armv7*" ]]; then
        MIN_VER=-miphoneos-version-min=7
    elif [[ "$IOS_SDK" == "iPhoneOS" && "$IOS_CPU" == "arm64" ]]; then
        MIN_VER=-miphoneos-version-min=7
    ...
    else
        echo "IOS_SDK and IOS_CPU are not valid. Please fix them"
        exit 1
    fi

I've got 'set -x' on and I see the compare is being made and missed
(https://travis-ci.org/noloader/cryptopp/jobs/660221143):

    # Echo variables
    IOS_SDK: iPhoneOS
    IOS_CPU: armv7s
    # set -x
    +++[[ iPhoneOS == \i\P\h\o\n\e\O\S ]]
    +++[[ armv7s == \a\r\m\v\7\* ]]
    +++[[ iPhoneOS == \i\P\h\o\n\e\O\S ]]
    +++[[ armv7s == \a\r\m\6\4 ]]
    ...

Why am I failing to match the string "armv7s" with "armv7*" ?

Thanks in advance.
