Android and iOS triplets are not recognized

[Jeffrey Walton]

Android and iOS triplets are still not recognized.

I'm using config.guess and confg.sub dated 2020- 2020-01-01. It is the
latest fetched using
https://www.gnu.org/software/gettext/manual/html_node/config_002eguess.html.

According to the docs at
https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Specifying-Target-Triplets.html:

    Autoconf-generated configure scripts ... target triplet, which has the form:
    ‘cpu-vendor-os’, where os can be ‘system’ or ‘kernel-system’

OK, sounds good.

Unfortunately, none of these are recognized:

    armv7a-android-linux
    aarch64-android-linux
    x86-android-linux
    i686-android-linux
    x86_64-android-linux
    amd64-android-linux

Swapping-in "aosp" (Android Open Source Project, which is the official
vendor name) for "android" also fails.

And none of these are recognized for Apple mobile devices:

    armv7a-apple-ios
    armv7s-apple-ios
    aarch64-apple-ios
    armv8a-apple-ios
    arm64-apple-ios

These devices have been around for about a decade. There is no reason
to fail to recognize them after 10 years.
