If the Android NDK and/or SDK are not setup, `kodev` will try to invoke
the `android-ndk` and/or `android-sdk` make targets. This can't be done
with `TARGET=android`, as `base/Makefile.defs` will error out trying to
call the (missing) compiler to get the target machine. Those rules need
to be available to all targets.
Relates to https://github.com/koreader/koreader/issues/9268
Requires https://github.com/koreader/koreader-base/pull/1504
Usage:
- `kodev release linux` for native package (same arch as host)
- `LINUX_ARCH=arm release linux` for armhf on a x86_64 host.
- `LINUX_ARCH=arm64 release linux` for arm64 on a x86_64 host.
It produces a `koreader-linux-$ARCH-$VERSION.tar.xz` archive, where $ARCH follows `uname -m` convention {x86_64, armv7l, aarch64}
To generate the debian package from the generic archive the following command is required
`./platform/linux/do_debian_package.sh path_to.tar.xz`
