This is needed to build mips64 ART in quick mode. Change-Id: I8a9e62389a3d4edb84bf1d6814d6594565bc98ba
The "generic_mips64" product defines a MIPS64 based non-hardware-specific target without a kernel or bootloader. It can be used to build the entire user-level system, and will work with the emulator. It is not a product "base class"; no other products inherit from it or use it in any way.
