Subject: Fix android builds (#4432)

* Terminate android build script early if any step fails

* Remove deprecated android types

* Use android NDK cmake support rather than cmake android NDK support as that support is better supported

* Android uses GNU strerror_r?

* Fix compilation

* Rebase

* Fix final issues

* Drop submodule changes

* Revert change

* Parentheses

* Lower api levels

* Don't use GNU strerror_r for Android
