bionic: mark bionic/android-ndk as obsolete

Support for bionic was dropped by GCC some time ago. There are patches
for older GCC versions but those are difficult to maintain and the
version of the android-ndk they support is of little use. Mark all of
the existing bionic support as obsolete so it can be removed after the
next release.
