"aaaxbb", where "aaa" is an offensive word and "bb" is not,

This CL enables Address Sanitizer for native host test. Note that
production build is not affected with this change.  ASan is enabled
only in static lib for test executables.

Change-Id: I2c8e99b8c55e611e86f74579f24a63ac949bb02d

It turned out that building native code for host environment
is not supported in NDK build.  Hence this CL makes the host
native test available only as a part of platform build to
avoid accidental build breakage in unbundled build.
