This should safe to select now. Note that proc-v7.S still does not
do anything with multiarch to configure it. So the bootloader still
needs to enable it, or it needs to be done in the machine init like
n900 does.

So applying into omap-for-v4.7/fixes as it can solve some mysterious
app crashers with armhf at least.
