Don't define |r_debug| and |link_map| on Android releases 21 and later

Browse source 
NDKs for Android 21 and later have the data structures |r_debug| and
|link_map| defined in their header files. Defining them multiple times
generates a compiler error.

This patch protects both data structures from definition on Android 21
and later.
