CCing linux-kernel for more exposure.

PING.  I'm waiting on a reply from anyone on the kernel side of things
to see whether they have an issue with reserving values for AT_HWCAP3
and AT_HWCAP4.  

I'll note reviews from the GLIBC camp did not have an issue with the below patch.

fwiw, aarch64 is quickly filling up AT_HWCAP2 so this will be
useful for arm64 too eventually, but we are not in a hurry.
