Are all SDK-supported devices ARMv7?

No they aren't but V8 only compiled to me for ARMv7 devices using vfpv3 or up arguments (like VFPv3-D16, VFPv3-D32, etc) are supported to compile. ARMv6 should be compiled with VFPv2 that is not supported for V8 anymore.

Okay, fair enough. If you can remove the unused function and squash the commits into a single commit with a nice commit log (see git log configure for examples), I'll land it for you.

why are we touching the armv6 block in this commit if this is specifically targetting only armv7?

I added those macros just as plus to complete the list of ARM macros in compilers. Are not a must have to compile for Android but is good to have a complete list of macros.
