i#7262: fix toolchain-android.cmake name (#7263)

`ci-package` is failing in generating Android 32 bit package because
`toolchain-android.cmake` was renamed as `toolchain-android-gcc.cmake`.
This is blocking all package builds.

We also fix the name in the doc that explains how to cross-compile for
ARM Android.
