That's not completely clear. It would certainly be true if the compiler were included on the phone, whether or not the compiler was actually used. But I was more addressing the general comment that Google doesn't care about GPLv3 than the specific issue of GCC. If the kernel were GPLv3, for example, there would be an issue with what Samsung is doing.
