building for -march=armv6 as happens when building allmodconfig. Since I have not been able to identify a way to override the compiler architecture selection per file add a Kconfig dependency to ensure this code is not built if V6 support is enabled.
I already proposed this solution to override the compiler architecture, in the same pattern as other similar code in the same directory.

My using 'CFLAGS_<obj> += <flags>', you can compile in v7.
I tried that but it wasn't doing the right thing for me - it appeared since the compiler ends up getting both -march=armv7-a and -march=armv6 it complained that it couldn't satisfy both options. It might be that this is version dependant or the actual cause wsa something else, I didn't investigate too hard.
If you ever see revisit this or see this again, I'd be interested in seeing the gcc args (make V=1) and version that failed. My fix worked for me, and I'll likely use it for the next revision if I don't find a good reason not to.
Thanks, Brian
