We cannot find library dependencies to add to a target's ordered
libraries list by searching the build directory because the build
directory may contain libraries that appear to be dependencies but are
in fact unrelated libraries that share a name with a system library
that the target depends on. For example, we may be building a target
that depends on the system's libGLESv2.so, and the build directory may
contain a library named libGLESv2.so as a result of building ANGLE. The
resulting APK would try to load libGLESv2.so using the crazy linker,
which might fail to load the system's library.

The solution is to use GN's write_runtime_deps feature to export the
runtime dependency list from the build system and create an ordered
libraries list from that.
