Remember that we just added support for AT_HWCAP3 and AT_HWCAP4.
Neither is actually being used yet, but in the not too distant future,
Power and Aarch64 will start using them.  Would those exacerbate the
GLRO issue?  If so, probably handling their pretty-printing another way
might be best?

I like having an easy way to dump out the HWCAP* names and LD_SHOW_AUXV=1
was an easy way to do that.  That said, I can come up with a different
way to do that if handling the pretty-printing would cause issues with
glibc updates.
