Force emulator to quit if it's built w/o global register variable support
Clang and llvm-gcc don't support global register variable (GRV) crucial
to emulator (where a register is reserved to point to target architecture
state for better code-gen). Clang and llvm-gcc are provided in recent
Xcode to replace the original gcc with GRV support. MacOSX developers
may accidentally install newer Xcode and break emulator.
This CL allows emulator (and the rest of Android tree) to build but forces
emulator to quit if it's built w/o GRV support. Developers build
Android tree with clang or llvm-gcc can still get good system image,
but they have to use emulators built the other way or from SDKs to run it.
