at /data/nativetest[64]/libvndksupport-tests/libvndksupport-tests, which
may will be in the system or legacy configuration, and either the "sphal"
or "default" namespace will be visible.

libvndksupport is a new LL-NDK library that provides vendor-visible APIs
for platform-only functionalities of other LL-NDK libraries. Currently,
it provides android_(load|unload)_sphal_library which abstracts the
platform-only APIs of libdl (android_get_exported_namespace, etc.)
